Given the function: f(x) = 2x3 - 3/2x, find f(-4).
a) -134
b) -128
c) -126
d) -122

D) -122

Step-by-step explanation:

Given:

We need to find f(-4).

Now by substituting the value of x =-4 in above equation we get;

By using PEDMAS we will solve for exponential function first we get;

Now we know that

So we get;

Now using PEDMAS we will solve division.

Now using PEDMAS we solve multiplication.

Finally by subtraction we get;

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
