There is only one statement that is true: B. The graph of the function is a parabola.
<h3>How to study and interpret the characteristics of quadratic equations</h3>
In this question we have a <em>quadratic</em> equation, whose characteristics have to be inferred and analyzed. We need to prove each of the five choices presented in the statement:
Choice A:
If we know that x = - 10, then we evaluated it at the function:
f(- 10) = (- 10)² - 5 · (- 10) + 12
f(- 10) = 162
False
Choice B:
By analytical geometry we know that all functions of the form y = a · x² + b · x + c always represent parabolae.
True
Choice C:
The <em>quadratic</em> function opens up as its <em>leading</em> coefficient is greater that 0.
False
Choice D:
If we know that x = 20, then we evaluate it at the function:
f(20) = 20² - 5 · (20) + 12
f(20) = 312
False
Choice E:
If we know that x = 0, then we evaluate it at the function:
f(0) = 0² - 5 · (0) + 12
f(0) = 12
There is only one statement that is true: B. The graph of the function is a parabola.

Answer:
26, 27, 28, 29
Step-by-step explanation:
Let the first integer be x.
Then, (x)+(x+1)+(x+2)+(x+3) = 110
=> x+x+1+x+2+x+3 = 110
=> 4x+6 = 110
=> 4x = 110-6
=> 4x = 104
=> x = 104/4
=> x = 26
So, the four consecutive integers are:
1. x = 26
2. x+1 = 26+1 = 27
3. x+2 = 26+2 = 28
4. x+3 = 26+3 = 29
