Find an equation of the tangent line to the curve: 7*x*e^(x)+8 at (0,8)
Derivative I guess?
The Attempt at a Solution
I know you have to take the derivative of the equation given which I think is
7*x*e^(x) + 7*e^(x)
Then you plug it into slope intercept form: y-y=m(x-x)
I did this and got y-8=(7*e^(x)*(x+1))*x, but apparently that's not right...
What did I do wrong? Maybe i just typed it in wrong?
