Question

If f(x) = -7x4 - 4x3 - 8x2 + 12 ; find f(-3)

Answer 1

−519

Explanation:

Use the given functions to set up and simplify f(−3).

Answer 2

Explanation:

f(x)=7x⁴-4x³-8x²+12

now keep (-3 )in place of x

f(3)=7(-3)⁴-4(-3)³-8(-3)²+12

f(3)=7(81)-4(-27)-8(9)+12

f(3)=567+108−72+12

f(3)=619
