Answer:
-8, -3, 2 ad 7
Explanation:
This graph shown is a polynomial function. The solution is the point where the curves cuts the x axis. From the diagram we can see that the curves cuts the x axis at four points.
The points are at x1 = -8, x2 = -3, x3 = 2 and x4 = 7
Hence the real solutions to the function f(x) = 0 are -8, -3, 2 ad 7
