How do you find the asymptotes of a rational function?To find the asymptotes of a rational function, identify vertical asymptotes by setting the denominator equal to zero and solving for x. Horizontal asymptotes depend on the degrees of the numerator and denominator: if degrees are equal, divide leading coefficients; if numerator’s degree is lower, y=0; if higher, no horizontal asymptote. Oblique asymptotes occur if the numerator’s degree is one higher than the denominator’s, found by polynomial division.

What is the difference between a chemical change and a physical change?
What is the difference between a chemical change and a physical change?A chemical change involves the formation of new substances with different properties, often irreversible, and involves breaking/forming chemical bonds. A physical change affects the form or state of a substance without altering its chemical composition, such as melting, freezing, or dissolving, and is usually reversible.
What is the derivative of the function f(x) = 3x^2 + 2x + 5?
What is the derivative of the function f(x) = 3x^2 + 2x + 5?The derivative of the function f(x) = 3x^2 + 2x + 5 is found by applying the power rule to each term. The derivative of 3x^2 is 6x, the derivative of 2x is 2, and the derivative of the constant 5 is 0. Therefore, the derivative f'(x) = 6x + 2.
What are the primary causes of global warming, and how can we mitigate its effects?
What are the primary causes of global warming, and how can we mitigate its effects?The primary causes of global warming include the burning of fossil fuels, deforestation, and industrial processes, which increase greenhouse gas emissions. Mitigation strategies involve transitioning to renewable energy sources, enhancing energy efficiency, reforestation, and implementing policies to reduce carbon emissions. International cooperation and personal lifestyle changes are also crucial.
How do you solve a system of linear equations using the substitution method?
How do you solve a system of linear equations using the substitution method?To solve a system of linear equations using the substitution method, first solve one equation for one variable. Substitute this expression into the other equation. Solve the resulting equation for the second variable. Finally, substitute back to find the first variable.
How can you find the length of the missing side in a right-angled triangle if you are given the lengths of the other two sides?
How can you find the length of the missing side in a right-angled triangle if you are given the lengths of the other two sides?To find the length of the missing side in a right-angled triangle, use the Pythagorean Theorem: a² + b² = c², where ‘c’ is the hypotenuse. If you know the hypotenuse and one leg, rearrange to find the other leg: a = √(c² – b²) or b = √(c² – a²).
How did the Industrial Revolution lead to the rise of urbanization and what were its effects on the structure of society?
How did the Industrial Revolution lead to the rise of urbanization and what were its effects on the structure of society?The Industrial Revolution spurred urbanization by creating job opportunities in factories, leading to mass migration from rural areas to cities. This shift transformed societal structures, fostering a growing middle class, altering family dynamics, and exacerbating class divisions. Urbanization also prompted advancements in infrastructure, healthcare, and education, while contributing to overcrowding and poor living conditions for the working class.
How does the human body regulate blood pressure through the nervous and endocrine systems?
How does the human body regulate blood pressure through the nervous and endocrine systems?The human body regulates blood pressure through the nervous system by using baroreceptors that detect changes in blood pressure and send signals to the brain, which then adjusts heart rate and vessel dilation. The endocrine system regulates blood pressure by releasing hormones like adrenaline, which increases heart rate, and aldosterone, which controls blood volume.
What is the difference between hardware and software in a computer?
What is the difference between hardware and software in a computer? Hardware refers to the physical components of a computer, such as the CPU, RAM, hard drive, and motherboard. Software, on the other hand, consists of the programs and operating systems that run on the hardware, enabling it to perform specific tasks. While hardware is tangible, software is intangible and can be easily modified or updated.
What is the difference between mean and median?
What is the difference between mean and median?The mean is the average of a data set, calculated by summing all values and dividing by the number of values. The median is the middle value when the data set is ordered from least to greatest. The mean is sensitive to outliers, while the median is more robust in skewed distributions.
