The real solutions of f(x) = 0 are: x = -8 , x = -4, and x = 7.
Another term for x-intercepts are the solutions, the roots, or the zeroes of a function. When given a graph and asked to find the solutions, we can simply search for where the graph touches the x-axis at a distinguishable point and these would be our solutions. In this case, the function touches the x-axis at, x = -8, x = -4, and x = 7. These are the solutions.
