1. The problem statement, all variables and given/known data Find an equation of the tangent line at the indicated point on the graph of the function. y=f(x)=x^3/4 , (x,y)=(6,54) 2. Relevant equations 3. The attempt at a solution I did the derivative which I get 3x^2/4 and then I plugged in the 6 and get 162. Is that the whole answer? right answer? it's asking for an equation and 162 doesn't look like an equation to me.
