Question

If g(x)= 3+x+e^x, find g,inverse,(4)

Answer 1

In an inverse function, the input or x is the y or output of the uninverted function. So set 3+x+e^x=4. Do you follow

Answer 2

yes

Answer 3

So you solve, where x+e^x=1.

Answer 4

got cha

Answer 5

x=0, right?

Answer 6

how did you get rid of the e^x

Answer 7

I didn't really get rid of it, I just realized that e^0=1, which is what I wanted from the problem. You could set the whole thing equal to zero and graph it.

Answer 8

okay
