SOLUTION: Given that y = 4x^2-x-4, find the approximate percentage change in y as x increases from 2 to 2.02.

Question 1192303: Given that y = 4x^2-x-4, find the approximate percentage change in y as x increases from 2 to 2.02.

x = 2, dx = Δx = 0.02





dy is approximately Δy, so

the fractional change is approximately 
0.3/2 = 0.15 which equals the approximate
percentage change, 15%.
