The degree of a polynomial will always tell us the maximum number of solutions
You have a second degree polynomial, so there are two possible solutions.
They are

The diagram below shows that the zeros are at (-3.854,0) and (2,854, 0), which are the decimal equivalents of the roots.
Answer:
C
Step-by-step explanation:
We are given the graph of f and that:
And we want to determine the values of x for which g has a point of inflection.
By the Fundamental Theorem of Calculus:
Thus:
g(x) has a point of inflection if and only if g''(x) = 0 and g''(x) changes signs around the point.
Since g''(x) = f'(x), g''(x) = 0 when f'(x) is 0. This happens at x = 2 and x = 5.
And at both x = 2 and x = 5, f'(x) changes signs before and after. Thus, g''(x) has inflection points at both x = 2 and x = 5.
The correct answer is C.
