Question

Consider the function:h(x) = -5x3 + 3x2 + 4x + 4Step 2 of 2 . Find the value of h(3).

Answer 1

We have the next equation:

$h(x)=-5x^3+3x^2+4x\text{ +4}$

Find the value of h(3) replacing 3 when we have an x on the equation.

$h(3)=-5(3)^3+3(3)^2+4(3)+4$$h(3)\text{ = -5(27) +3(9) +12+4}$$h(3)\text{ = -135+27+12+4}$$h(3)\text{ = -135+43 = -92}$

The value of h(3) = -92
