Can someone help me with this question.

i think you should have a go before asking. there isn't much to the question and it is pretty straight forward

Well, simply...

If y = e^x
y' = 1e^x
which is just y' = e^x

Then sub in x = 3 to find the gradient (make sure you leave this in exact form as the question asks exact form i.e. m = e^3), and use point-gradient formula to find the equation.

Also find y.

I don't feel like giving the whole working out method cause it seems simple enough to do but if you wish for a full working out method then I'll write one up.

Anyone who has paid any attention in class should be able to do this question.
It doesn't bode well for the future.
