Hi, I could not figure out two questions in my homework. The first problem deals with a piecewise function.
9
g(x)dx, where g(x)={1, x> 0 and x^3, 1 < x < 4 and sqrt x, 4 < x < 9
0
also,
Find the area below the interval [-2, -1], but above the curve y=x^3
Does this just mean
-1
(x^3)dx
-2
??
Ok hi
I attach my answer the second question you just should multiply the answer by -1

sorry, I'm a little confused. So do I just add an absolute value sign after the integration sign, then calculate?
I've gotten negative numbers for some of my integration problems and didn't get marked wrong. Is it because it says "but above the curve y=x^3?"
I thought that just meant the area between the interval and the curve. Thanks!
