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.
