1. The problem statement, all variables and given/known data Find an equation of the tangent line to the curve: 7*x*e^(x)+8 at (0,8) 2. Relevant equations Derivative I guess? 3. 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?
