Question

@triciaal

2) Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to Heinz the other key features of g(x).
g(x) = x^3 – x^2 – 4x + 4(i chose this one)
g(x) = x^3 + 2x^2 – 9x – 18
g(x) = x^3 – 3x^2 – 4x + 12
g(x) = x^3 + 2x^2 – 25x – 50
g(x) = 2x^3 + 14x^2 – 2x – 14
I really need some help

Answer 1

Answer 2

why did you pick that one?

what happens when x = 0
what happens when y = 0

Answer 3

I chose that one because it seemed as if it would have been easier to graph

Answer 4

the constant is 4 so what are the factors of 4
1,4,2,2 including the negatives
find when you substitute one at a time if g(x) = 0 then (x-#) is a factor of the function.
note that after you find the first factor you can just divide into the g(x)
the quotient will be a quadratic you factor to get the other values.

Answer 5

same for any one

Answer 6

yes this looks like an easy one.
I looked at it and saw
x^2(x-1) - 4(x-1)
(x^2 - 4)(x - 1)
(x-2)(x + 2)(x-1)
x=2, x = -2, x = -1
(-1, 0), (-2, 0), (2, 0)

Answer 7

thank you

Answer 8

you already had (0,4)
