Four polynomial functions are shown below:

f(x) = x^3 + 3x^2 - 4x - 12
g(x) = x^3 - 3x - 2
p(x) = x^2 + 3x + 2
t(x) = x^2 + x - 2

Which of the following functions has 1 and -2 as its zeros?

a.) f(x)

b.)g(x)

c.) p(x)

d.) t(x)

Answer 6

graph them see which one touches the x-axis

Answer 7

so b

Answer 8

Or work backwards:
So we know \[\LARGE x=1, -2\]
\[\LARGE (x=1)(x=-2)\]
\[\LARGE (x-1)(x+2)=0\]
Now distribute.

btw, 2 roots=x^2 not x^3

So not "B" but if you wanna take his word for it, go for it.
