The first derivative is found using the quotient rule.
f'(x) = [x(x+8)] / [(x+4)^2]
The second derivative is found using the product rule.
f''(x) = [32] / [(x+4)^3]
f''(5) = [32] / {[(5)+4]^3}
f'(x) = [x(x+8)] / [(x+4)^2]
The second derivative is found using the product rule.
f''(x) = [32] / [(x+4)^3]
f''(5) = [32] / {[(5)+4]^3}
