Exercise 53 Page 138

Use the fact that the solutions of an equation are the x-intercept of the graph of the related function.

None

Practice makes perfect

We know that the solutions of an equation can be identified by finding the x-intercepts of the graph of the related function. If the related function does not have any x-intercept, then the equation has no solution.
