I have a question to find the equations of the tangent line and the normal line to the curve at the given point. I can find the equation for the tangent line easily but I am not sure what a normal line is and there is no example that I can find.
$y=x^4 + 2e^x$ at (0,2)
From that I do see that if I plug in 0 I get 2 as a result so my guess was that if I plug in another number I can use that to get the slope but it gave an incorrect answer.
