Question 1152470: Given the function g(×)=9-x2, evaluate g(x+h)-g(×)/h
Answer by Celi(1)   (Show Source):
You can put this solution on YOUR website! Step 1) Find g(x), which is given as 9-x2.
Step 2) Find g(x+h), which would be g(x) where all x's are replaced with (x+h), therefore g(x+h)= 9-(x+h)2.
Step 3) Plug g(x) and g(x+h) into g(x+h)-g(h)/h
It would look like (9-(x+h)2)-(9-x2)/h
Side note: Make sure to double check whether that x2 is x squared or two times x, and whether the whole thing to evaluate is divided by h (like [g(x+h)-g(x)]/h) or if it is just g(x) that is divided by h.
