Answer

Explanation:

Step1: Find f(x + h)

Substitute (x+h) into (f(x)=6 - 8x^{2}). [ \begin{align*} f(x + h)&=6-8(x + h)^{2}\ &=6-8(x^{2}+2xh+h^{2})\ &=6-8x^{2}-16xh - 8h^{2} \end{align*} ]

Step2: Calculate f(x + h)-f(x)

[ \begin{align*} f(x + h)-f(x)&=(6-8x^{2}-16xh - 8h^{2})-(6 - 8x^{2})\ &=6-8x^{2}-16xh - 8h^{2}-6 + 8x^{2}\ &=-16xh-8h^{2} \end{align*} ]

Step3: Determine the difference quotient

[ \begin{align*} \frac{f(x + h)-f(x)}{h}&=\frac{-16xh-8h^{2}}{h}\ &=\frac{h(-16x - 8h)}{h}\ &=-16x-8h \end{align*} ]

Answer:

a. (6-8x^{2}-16xh - 8h^{2}) b. (-16xh-8h^{2}) c. (-16x - 8h)
