Find an equation of the tangent line to the the graph of the function f(x) = (x^(1/2))(9-6x^2
We note that, when x=4,
the corresponding point on the graph is given by (4,f(4))=(4, ___ ) and that the slope of the tangent line is f ′(4)=
Therefore the equation of the tangent line is y =
I'm not sure whether or not to cancel out the x's and have x^-1/2 at the top and then use the product rule. or use the quotient rule straightaway. Am I not seeing anything that's there?
I also get the slope 2.375
final equation I got (which is way off)
y = 2.375x-53
help would be appreciated!
