Use the function below to find f(–4). f(x) = 2x

Find out the value of f(–4) by using the function  f(x) = 2x  .

To prove

As given the function in the question as follows

f(x) = 2x

Now find for f(–4) .

Put x = - 4 in the function given above

Thus

 f(-4) = 2× -4

Simplify multiply 2 and -4 .

  f(-4) = -8

Therefore the value of f(–4) is -8  by using the function  f(x) = 2x .

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
