How do I find f'(x) when f(x)=7/x?

7 a) Graph the function f(x) = - X b) Draw tangent lines to the graph at the points whose x-coordinates are 0 and 1 f(x + h) - f(x) c) Find f'(x) by determining lim h-0 h d) Find f'(0) and f'(1). These slopes should match those of the lines from part (b) c) f' (X) =
