Anyone know how to solve this? Recently goes this as a question and kept getting stuck after factoring x from the bottom.
We haven't gotten this far into our lectures, we've just been applying limits.Look at that again. Both the numerator and denominator go to 0 when we take the limit. It may be undefined and it may not be.
Do you know how to use l'Hopital's rule?

This is fine! Remember, lim (a+b) = lim a + lim b, and the same works for products. Cancel out the x, use the e^x limit, and bring it all together in the end.Heres what i've tried, I have a feeling I did something wrong and that it isn't actually undefined.

Because once I insert the limit then 3((e^x)-1)/x = 3 because ((e^x)-1)/x=1
However 2x+9x^2 = 2(0)+9(0)^2
So all of it will be (7+3(1))*(1/0) which will give me undefined.
