A "zoom" on the graph of y = f(x) near (xo, Yo) (with yo = f(xo)) with magnification factor M (the same in both r and y directions) is the graph of the function defined by f(ro + x/M) = yo + y/M. Prove that if f is differentiable at x0, then the zoom converges to the straight line through the origin with slope f'(xo), as M → o. What happens to the zoom of Jx| near the origin?

Question
A "zoom" on the graph of y = f(x) near (ro, Yo) (with yo = f(x0))
with magnification factor M (the same in both z and y directions)
is the graph of the function defined by f(ro + x/M) = yo + y/M.
Prove that if f is differentiable at xo, then the zoom converges to
the straight line through the origin with slope f'(r0), as M → o.
What happens to the zoom of |x| near the origin?
