Forward Difference Approximation For the given ordered pairs

Forward Difference Approximation For the given ordered pairs, (2, -4) and (0, 1), find the forward difference approximation to the derivative. Give your answer to 2 decimal places. Your Answer: ____________

Solution

the forward difference approximation is f(x_n+1)+f(x)/1(since height is 1)
difference of y-axis values/difference of x-axis values
= (-4-1)/2-0
=-5/2
=2.50
