Question

Evaluate: Integral of... (photo)

Answer 1

Answer? :-)

Answer 2

here are the answers given @bmp

Answer 3

What did you pick?

Answer 4

Any specific question about this? Have you tried it out yet?

Answer 5

the fourth answer

Answer 6

Incorrect.

Answer 7

oh dang which one is it

Answer 8

Remember the power rule: \[ x^n = \frac{x^{n+1}}{n+1}\]And remember to break it into two integrals.

Answer 9

@SmoothMath I am trying to get the answer

Answer 10

\[ \int 3x^2dx - \int 4xdx\]

Answer 11

@bmp I keep ending up with that answer i am not sure where i am going wrong. is it by chance 1 instead of -1?

Answer 12

Nope. Did you get: \[ x^3 - 2x^2 \]for the antiderivative?

Answer 13

no i mustve messed up there. So with that as the antiderivative the answer would have to be 3

Answer 14

Yeah, it is. But rework your integral to make sure you get the correct antiderivative. The integrals above should simplify to \[3 \int x^2 dx - 4\int xdx \]

Answer 15

yes, 3.

Answer 16

oh okay thanks @bmp i just needed to rework my integral. thankyou also @alienbrain
