My question is in the picture I tried to multiply -7 on both sides and got -147 I don't know if it's correct or if it's the right way to do it.

Consider the function f(x)=-5x+3 what is f(-2)

List x1, x2, x3, x4 where xi is the left endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 4 and x = 6. a 4, 4.5, 5, 5.5 b 4.5, 5, 5.5, 6 c 4.25, 4.75, 5.25, 5.75 d 4, 4.2, 5.4, 6

With number 11 ( show how you got the answer)
