Question

The graphs of f(x) and g(x) are shown below:

PIC


What are the solutions to the equation f(x) = g(x)?


x = −3, 4

x = −3.8, −0.4

x = −3.8, 3

x = 6.5, −6

Answer 1

-3.8, 3

Explanation:

The solution to a system is where the graph cross each other. If you look to where they intersect to the left of the origin, where x is negative, it appears that they intersect ALMOST at -4, but not quite. So -3.8 is going to have to do since we don't have the equations of either graph to find the exact values of x. To the right of the origin, where x is positive, the graphs cross where x = 3..

Answer 2

x = −3.8, 3

Explanation:

The solutions to f(x) = g(x) are the x-coordinates of the points of intersection of their graphs. Those x-values appear to be about -3.8 and +3.
