Question

Consider the graphs below, which give m(x) in the left graph, in black, and n(x) in the right graph, in blue. Both functions have a sharp corner at x=50.

Let h(x)=n(m(x)). Find a point x where h'(x)=1.44
x=

40< m(x) < 50

Answer 1

you know, posting the same question three times does not get you any points, nor any faster help.
