Question

The area of the region between the graph y=3x^2+2x and the x axis from x=1 to x=3 is?

Answer 1

integrate top curve minus bottom curve. the bottom curve is the x axis itself (y=0). the top curve is probably 3x^2 + 2x,
so integral 3x^2 + 2x - 0

Answer 2

use power rule here for integrating
x^n = n*x^n-1

Answer 3

what about the x=1 and x=3?

Answer 4

thats the upper and lower limits

Answer 5

so i plug that in and add them both or subtract?

Answer 6

You have to draw a rough draft to get an idea what you are doing.
