Question

Please help, this is timed. 50 points for each answer. What is the difference quotient of f(x)?

Answer 1

x travels from -5 to 5

y stays constant at 8

Quotient is given by y/x

Hence our answer is .

$\\ \sf\longmapsto \dfrac{8}{h}$

Here h can't be 0 as it makes the diction undefined.

$\\ \sf\longmapsto \dfrac{8}{h},h\neq 0$

Option B
