Hey! A few questions here:
1) Find the equation of the tangent line to the parabola y=6-5x+3x^2 at the point where x=1. I got y=x+3... but the book says y=x+2.
2) Fine the equation of both tangent lines to the curve y=x^3-x that are parallel to the line 22x-2y+1=0. I understand y=11x+16.. but not the second answer.. y=11x-16.
3) What's the derivative of 5^x-1?
ANY HELP IS VERY, VERY, VERY MUCH APPRECIATED! Thanks. :)
