For the function, f(x) = -5x 2, find f(-4).

The value of f(-4) = -80

Step-by-step explanation:

It is given that,  f(x) = -5x²

To find the value f(-4)

Let  f(x) = -5x²

To find the value of f(-4), substitute -4 instead of x

f(-4) =  -5 * (-4)²

 = -5 * 16      [ since (-4)² = -4 * -4 = 16 ]

 = -80

Therefore the value of f(-4) = -80
