I could really use some help...a littel confused. I know that the difference quotient is f(x+h)-f(x)/h
The question in the assignment asked me to use the difference quotient to evaluate f(x)= x^2+13
this is how i did it, could you please let me know where I went wrong...
x^2 +2hx+h^2-x^2 +13/h
the two x^2 are cancelled
the h's cancel, leaving 2x+h+13/2
my final anwer was 2x+h+13/h
I didn't get it correct and im not sure where I went wrong...
