Find f(g(x)) f(x)=-6x-1 , g(x)=4x^2

$f (x) = - 6 x - 1$ , $g (x) = 4 x^{2}$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (4 x^{2})$ by substituting in the value of $g$ into $f$ .

$f (4 x^{2}) = - 6 (4 x^{2}) - 1$

Step 3

Multiply $4$ by $- 6$ .

$f (4 x^{2}) = - 24 x^{2} - 1$
