Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I am having a bit of trouble, i am getting ready for an exam, one the questions i have asks

"given the curve y = e^x, draw tangents to esitmate the gradients of the curve when

a)x=0, b)x=1, c)x=-1,

Now i know the answers are:

a) 1 b) 7.39 c)0.05

However the toruble i am having is understanding hwo to get to those points. For the first i got to this:

x= 0

dy/dx|x=0 =0e^(0-1), but then where do i go to get to the point where the answer become 1? Could someone help me with the others, i am having a large amoutn of difficulty to get this to click in my head, if anyone could help me out i would be very apreciable.
