I need to evaluate:

f(x + h) - f(x) / h

and simplify if:

f(x) = x^2 - 2x

I don't need the answer, but just how to attempt this problem. I know that I need to replace x with x^2 - 2x, but Im not sure what to do with the variable h. Thank You.

Examine the rise in gasoline prices from 1997 to 2006. The price of regular unleaded gasoline in January 1997 was $1.26 and in January 2006 the price of regular unleaded gasoline was $2.31 (Bureau of Labor Statistics, 2006). Use the coordinates (1997, 1.26) and (2006, 2.31) to find the slope (or rate of change) between the two points.
