I can't figure out how to solve this problem:
finf k such that the line is tangent to the graph of the function.
x^2-kx y=4x=9
Can someone help me understand this problem?

Did you mean that we were to find k, such that is a tangent to the curve ?
If so, remember that the derivative of a function gives the equation of the tangent of that function.
If you differentiate , you get . What you must do is compare this to in order to find k.
