Question

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Answer 1

x = - 7 , x = - 3 , x = 0 , x = 4

Explanation:

the solution to f(x) = 0

are the values of x on the x- axis where the graph crosses the x- axis

the graph crosses the x- axis at 4 places , that is - 7, - 3, 0 , 4

the real solutions to f(x) = 0 are then

x = - 7 , x = - 3 , x = 0 , x = 4
