Question

f(x)=3x + 2
g(x)=-2x^{3}
h(x)=-4x^{2}-2x + 5
find the value of h(5)
a -25
b -115
c 95
d -105

Explanation:

Step1: Substitute x = 5 into h(x)

$h(5)=-4\times5^{2}-2\times5 + 5$

Step2: Calculate the powers

$h(5)=-4\times25-2\times5 + 5$

Step3: Perform multiplications

$h(5)=-100 - 10+5$

Step4: Perform additions and subtractions

$h(5)=-105$

Answer:

D. -105
