Use the given recursive rule to find the given term. Given f(1)= 5 f(n)=f(n-1) + 7
f(1)=5
f(2)= f(1)+7= 12
f(3)= f(2) +7= 19
f(4) = f(3) +7 = 26

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
