Question

alg 2 help? functions?

Answer 1

this is what i got.

The function f(x) is a difference of squares. ---- y = x^2 -9
The function g(x) is a sum of squares. ---- y = x^2 9
The function h(x) is a perfect square trinomial. ---- y = x^2 6x 9
The function j(x) can only have a GCF factored out of it. --- y = x^2 2x

1st y = (x 3)(x-3)
2nd is prime for real numbers
3rd y = (x 3)^2
4th y = x(x 2)

Answer 2

my teacher said "actually show how you would factor each if possible. Also on the last two you are missing + and - symbols, please add so we can grade accurately"
