Question

Given the two functions below, what is the x-intercept of g(x)?

f(x) = x2
g(x) = f(x –7)

Answer 1

what will be gx ?

Answer 2

If your asking me i don't know. lol
That's the whole question

Answer 3

fx = x^2 right?

Answer 4

Yes

Answer 5

so.. g(x)= f(x-7) .. that basically means g(x) is equal to f(y) where value of y would be x-7..
so all you need to do is..put x-7 in place of x in f(x)..
that would give you g(x)=(x-7)^2..
yeah?

Answer 6

f(g) = (x-7)^2
y=0 @ x=7

Answer 7

wrong anu..
put g(x)=0 and find the value of x..

Answer 8

Yes @yrelhan4 u r right its a typo :)

Answer 9

Yes your right @yrelhan4

Answer 10

thanks everyone :)
