Best ResponseYou've already chosen the best response.0the equation editor seems to have distorted the equation ; can you verify it?

Best ResponseYou've already chosen the best response.0I was given a takehome test, and I'm supposed to teach myself definite integrals and have it due tomorrow.

Best ResponseYou've already chosen the best response.0FTC says the definite integral = F(1)  F(1) but you have to find F(x) by taking antiderivative of f(x)

Best ResponseYou've already chosen the best response.1If you integrate 4e^x, you would get 4e^x. Then, integrate 1 and you get x So then you have 4e^x  x evaluated from 1 to 1

Best ResponseYou've already chosen the best response.1if you sub in your values, you get (4e^1  1)(4e^1+1)

Best ResponseYou've already chosen the best response.0After the values are substituted in, do I just simplify?

kjp92123

Best ResponseYou've already chosen the best response.0So is the final answer (2)?

kjp92123

Best ResponseYou've already chosen the best response.0So is the answer just (2) by itself? Or is there anything on the opposite side of the equal sign?

math93

Best ResponseYou've already chosen the best response.1the integral of the original problem = 2, so "2" is the final answer
