Find the x-intercepts of the following polynomial function''
f (x) = x^2 - 2x - 80
1 answer:
Answer:
(-8 , 0)
(10 , 0)
Step-by-step explanation:
(-8)^2 - 2(-8) - 80 = 0
(10)^2 - 2(10) - 80 = 0
then (-8 , 0) and (10 , 0) are x-intercepts Of the polynomial f
the others are not because (for instance):
(8)^2-2(8)-80 =
:)-32
