$f (x) = x + 11$ $g (x) = 2 x^{2} - x - 6$

Step 1

Set up the composite result function.

$f (g (x))$

Step 2

Evaluate $f (2 x^{2} - x - 6)$ by substituting in the value of $g$ into $f$ .

$f (2 x^{2} - x - 6) = (2 x^{2} - x - 6) + 11$

Step 3

Add $- 6$ and $11$ .

$f (2 x^{2} - x - 6) = 2 x^{2} - x + 5$
