Answer:
C. 14
Explanation:
The given graph represents a polynomial function r(x).
We want to find an x-value that satisfies
r(x)=0.
The solution to the function whose graph is shown are the x-intercepts of the graph.
We can read from the graph that, the x-intercepts are;
and
.
Hence the solutions are x=-6 and x=14.
From the given options a solution to r(x) is 14.
The correct choice is C
