Question: f ( x ) = x 1 a)Find the equation of the normal line to the graph of f at the point where x =
f(x)=x1
a)Find the equation of the normal line to the graph of f at the point where x = -1. (The normal line to a curve C at a point P is the line through P that is perpendicular to the tangent line at P.) b)Sketch the graph of f and, underneath, on a new set of coordinate axes, the graph of f'.
