Answer 1

(fog)

f(g(x))

f (x) =x^2-3

f squares whatever is in its arms (x) and then subtracts 3.

g(x)=2x+1

g doubles whatever is in its arms and adds 1

Answer 2

f ( g(x) = f ( 2x+1 ) = ( 2x + 1) ² - 3

f squares whatever is in its arms (x) and then subtracts 3.

Answer 3

f ( g(x) = f ( 2x+1 ) = ( 2x + 1) ² - 3

We have to crank out this: ( 2x + 1) ² - 3

See what you get, okay?

Answer 4

yea

Answer 5

4x^2 + 4x -2

Answer 6

Yes,

f (g(x) = 4x² + 4x - 2
