What is the value of the dependent variable if the value of the independent variable is - 4?

f (x) = - 3x^2 + 5x

A.

28

B.

-44

C.

-68

D.

4

If you would like to know the value of the dependent variable if the value of the independent variable is - 4, you can calculate this using the following steps:

independent variable ... - 4 ... x

dependent variable ... f (x)

f (x) = - 3x^2 + 5x

f (-4) = - 3 * (-4) ^2 + 5 * (-4) = - 3 * 16 - 20 = - 48 - 20 = - 68

The correct result would be C. - 68.
