f%28x%29=2x%5E2-7x%2B3 Start with the given function


f%28-3%29=2%28-3%29%5E2-7%28-3%29%2B3 Plug in x=-3.


f%28-3%29=2%289%29-7%28-3%29%2B3 Square -3 to get 9.


f%28-3%29=18-7%28-3%29%2B3 Multiply 2 and 9 to get 18.


f%28-3%29=18%2B21%2B3 Multiply -7 and -3 to get 21.


f%28-3%29=42 Combine like terms.
