Question 304345: Hi here is the question:
Frieda is trying to find a function. She knows that f(-2)=0, f(-1)=9 and f(4)=0.
Which function is Frieda looking for?
(when i put the two Behind the x instead of in front, i mean x squared.)
A) f(x)=x2-2x-8
B) f(x)=-2x2+x+4
C) f(x)= -x2+2x+8
D) f(x)= 9x2-2x+4

x^2 is x squared
f(-2)=0, f(-1)=9 and f(4)=0.
if x=4 y=0
if x=-2 y=0
We have the two roots.
(x+2)*(x-4)=0
x^2-2x-8=0
A)
