Find h(5) using the equation.

• -25

• 25

• 3

• 7

• undefined

What is the slope between (0,9) and (5,4)

• x = -3

• x = 5

• y = 0

• y = 1

• x = -2

Choose the correct equation

• y = x(x-3)(x-2)

• y = x(x-3)²(x+2)

• y = x(x+3)²(x-2)

• y = -x(x+3)²(x-2)

True or False: All rational functions have horizontal asymptotes.

• True

• False

The end-behavior of a polynomial function can be determined using which of the following values of the function?

• f(0) and f(100)

• the factors and zeros

• the x-intercepts and y-intercepts

• the degree and leading coefficient

A polynomial function of degree 'n' has, at most, how many zeros?

• n + 1

• n

• n - 1

• none

Given a slope of 4 and the point (-3, 2), write the equation of the line that goes through that point in point slope form. Do not put spaces in your answer, and simplify (subtracting a negative is addition of a positive)

• (-∞, -3) U (2, ∞)

• (-∞, -3) U (1, 2)

• (-∞, -3) U (1, ∞)

• (-3, 1) U (2, ∞)
