f%28x%29=x%5E2%2B5x%2B7 Start with the given function.


f%284%29=%284%29%5E2%2B5%284%29%2B7 Plug in x=4.


f%284%29=1%2816%29%2B5%284%29%2B7 Square 4 to get 16.


f%284%29=16%2B5%284%29%2B7 Multiply 1 and 16 to get 16.


f%284%29=16%2B20%2B7 Multiply 5 and 4 to get 20.


f%284%29=43 Combine like terms.
