The answer to this question is the letter C:
-0.1*65 = -6.5
-6.5+110 + 103.5
The answer to 9≤c+1 is c ≥ 8
For this case we have that by definition, the roots, or also called zeros, of the quadratic function are those values of x for which the expression is 0.
Then, we must find the roots of:

Where:

We have to:
Substituting we have:

By definition we have to:

So:

Thus, we have two roots:

Answer:
