the expression (f(x + h) - f(x))/h for h ≠ 0 is called the difference quotient. find and simplify the difference quotient for the following function. f(x)=8x² + 10x + 2 the difference quotient is . (simplify your answer.)
Answer
Answer:
$16x + 8h+10$
Explanation:
Step1: Find $f(x + h)$
$f(x + h)=8(x + h)^2+10(x + h)+2=8(x^{2}+2xh+h^{2})+10x + 10h+2=8x^{2}+16xh+8h^{2}+10x + 10h+2$
Step2: Calculate $f(x + h)-f(x)$
$f(x + h)-f(x)=(8x^{2}+16xh+8h^{2}+10x + 10h+2)-(8x^{2}+10x + 2)=16xh+8h^{2}+10h$
Step3: Calculate the difference - quotient
$\frac{f(x + h)-f(x)}{h}=\frac{16xh+8h^{2}+10h}{h}=\frac{h(16x + 8h+10)}{h}=16x + 8h+10$
