Question

If f(x)=x^2-1 and g(x)=3f(x), graph g(x) and write the equation for g(x)

Answer 1

g (x) = 3x^2 - 3

Explanation:

Answer 2

For this case we have the following function:
f (x) = x ^ 2-1
We write now g (x):
g (x) = 3f (x)
Substituting values we have:
g (x) = 3 (x ^ 2-1)
Rewriting we have:
g (x) = 3x ^ 2-3
Answer:
The equation for g (x) is:
g (x) = 3x^2 - 3
