Find an equation to the tangent line to the curve at the given point. (So, I have to find the derivative, but Im stuck  not sure if I am doing this correctly). Function is y=x^(5/2) Point is \(\ (4,32). Please show me step by step! I'm really confused!

Best ResponseYou've already chosen the best response.1plug in x=4 to find the slope (m) of the tangent to the curve at that point.. use y= mx +b with the point they gave in order to find b

Best ResponseYou've already chosen the best response.0Oh Okay. I was trying to plug the derivative in for m, but I guess that isn't correct.
