Finding f(-5)


f%28x%29=x%5E2%2B6 Start with the given equation.


f%28-5%29=%28-5%29%5E2%2B6 Plug in x=-5.


f%28-5%29=25%2B6 Square -5 to get 25.


f%28-5%29=31 Add.

Finding f(4)


f%28x%29=x%5E2%2B6 Start with the given equation.


f%284%29=%284%29%5E2%2B6 Plug in x=4.


f%284%29=16%2B6 Square 4 to get 16.


f%284%29=22 Add.
