Question

Find the slope of the tangent line to the graph of f at the given point.
f(x) = √x at ( 36, 6)

A. 1/3
B. 12
C. 3
D. 1/12

Answer 1

You take the derivative of the function, and then plug in the point value for x. You should get 1/2√x as the derivative. After plugging in "36" for x, you should get 1/12. So D is the answer.

Answer 2

Oh, thanks! I had no idea Smokey was good at math. The more you know,

Answer 3

Trust me, I can't do math that I need to be able to do for my class, so I'm still a bit hesitant on things like this too. For future reference, "slope of the tangent line" generally means derivative, and giving it a specific point gives you a specific value at that spot on the line.
