Question

Identify the y and x-intercepts of g(x).

f(x) = x^2 -4

g(x) = f(x)-5

Answer 1

To find x - intercept, let y = 0 and solve for x, for y - intercept, let x = 0 and solve for y.
g(x) = (x^2-4)-5 since f(x) = x^2-4

Answer 2

Im so lost..I been struggling over this all yesterday and decided to give it a break.

Answer 3

That's ok, can you show me what you tried?

Answer 4

I know that the x intercept of F(x)=x^2-4 is -2 and 2. And that the y intercept is -4. But i don't know where to go from there.

Answer 5

@iambatman ?

Answer 6

You're just plugging in f(x) in g(x) and essentially doing the same thing

Answer 7

You will see g(x) becomes (x^2-4)-5 and you can find the x and y intercepts as before

Answer 8

So 3 and -3 and y intercept is -9?

Answer 9

Looks good to me!
