Posted: Fri Oct 30, 2009 1:56 pm
Hello,
The question is : For what value of b is the line y=10x tangent to the curve y=e^(bx) at some point in the x-y plane?
a) 10/e
b) 10
c) 10e
d) e^10
e) e
The correct answer is a.
I know that the derivative of the curve should be equal to the line however i couldn't make it. I would be very grateful to your help.
Thank you.
