Answer:

Based on the graph below, what is the total number of solutions to the equation f(x)= g(x) will be 3.

Step-by-step explanation:

The intersection points of both graphs would be the total number of solutions to the equation f(x)= g(x).

From the given diagram, it is clear that both the graphs intersect at three locations points or intersection points. The approximations locations of The intersection points of  both graphs are

  • (1.5, 4.125)
  • (-1, 0), and
  • (-2.5, -3.5)

Therefore, based on the graph below, what is the total number of solutions to the equation f(x)= g(x) will be 3.
