f(x)= x²(x – 2)³(x – 7)

Find and select each real zero and its multiplicity. (Look at your notes "Polynomial, Linear functions, Zeros". Week 26 in google classroom, this slide goes with the sample videos)

• 0 (Mult of 2), 2 (Mult of 3), 7 (mult 1)
• 2 (Mult of 3), 7 (mult 1)
• 0, 2, 7
• 2 (mult of 2), 7 (mult of 3)

f(x)=(x+4)(x-3)(x-2)

List the zeros for this function.

• x = -4, x = 3, x = -2

• x = -4, x = 3, x = 2

• x = -4, x = -3, x = 2

• x = 4, x = 3, x = 2
