Use the graph to solve the equation
We can identify one such point in the graph. Let's now find the x-coordinate of this point graphically.
This x-coordinate is not easily read from the graph, so we'll have to make an approximation. It's just a bit bigger than 3, so we'll use 3.1. This means that an approximate solution to the equation is We can verify this by substituting it into equation to see if a true statement is made.
The right-hand side and the left-hand side are approximately equal, so we have indeed found an approximate solution to the equation:
