Answer:

f(-3) =  -239

Step-by-step explanation:

f(x) = 10x³+4x²-5                      PUT THE EQUATION

f(-3) = 10x³+4x²-5                     Change f(x) to it's given value of x= -3

f(-3) = 10(-3)³+4(-3)²-5               Change all the x you see to -3 and simplify

f(-3) = -270 + 36 - 5                   Now add it all

f(-3) =  -239                             That is the final answer.
