2 cards from this section. Quick, good the night before a test.
Find the x-intercept of f(x) = (x + 3) / (x - 2).
Set the numerator equal to zero.
What is the y-intercept of g(x) = (2x - 4) / (x + 1)?
Evaluate g(0).
How do you find the x-intercept of a function?
Remember, you set the numerator equal to zero.
True or False: The y-intercept is found by evaluating f(0).
Think about what happens at x = 0.
Given the rational function p(x) = (x^3 - x) / (x^2 - 4), find all intercepts and discuss any asymptotes.
Factor thoroughly and observe limits for asymptotic behavior.
If q(x) = (2x^2 + 3x - 5) / (x - 1), determine the intercepts and behavior as x approaches 1.
Watch for cancellation of common terms and how it affects the graph.
