Hi everyone, i need help.
This is my problem:
Find a function f (x) such that its graph is similar to the one in the figure (the closer the better), moreover the tangent line to y = f (x) at the point where x = 5 cuts the x-axis at x = 4, and the tangent line to y = f (x) at the point where x = 4 cuts the x-axis at x = 3 (see the figure). Illustrate your work by drawing a picture.
