Evaluate the equation the you in the picture up above.

evaluate f(x) =

f(x) = -2x² + 4       Find f(4) --->  x = 4, so you need to substitute the number in for x in the function

f(x) = -2x² + 4  

f(4) = -2(4)² + 4       Square 4

f(4) = -2(16) + 4     Multiply -2 and 16

f(4) = -32 + 4     Simplify

f(4) = -28
