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

x travels from -5 to 5
y stays constant at 8
Quotient is given by y/x
Hence our answer is .
[tex]\\ \sf\longmapsto \dfrac{8}{h}[/tex]
Here h can't be 0 as it makes the diction undefined.
[tex]\\ \sf\longmapsto \dfrac{8}{h},h\neq 0[/tex]
