by Keitha Kjergaard

Multiple Choice

f(x) = (x-7)(x+2)(2x-4)

Find the zeros

• x = -7, -2, 4

• x = 7, -2, 4

• x = 7, -2, 2

• x = -7, 2, -2

Multiple Choice

g(x) = (3x+4)(x-2)(3x+12)

Find the zeros

• x = -4/3, 2, -4

• x = -4, -2, -12

• x = 4/3, -2, -12

• x = -4/3, -2, -4

Fill in the Blanks

Find the factored polynomial from the points

(-5, 0), (4, 0), (2, 0)

Multiple Choice

$$x\left(x-2\right)\left(2x-2\right)^2$$  

What is the degree of the polynomial?

• 3

• 4th degree

• 5th degree

• 2nd degree

Fill in the Blanks

f(x) = (x + 3)(2x-5)

g(x) = 3(x+3)(2x-5)

What happens to the output values of g(x) compared to the output values of f(x)?
