The answer would be B. (228-89) because you are trying to find the difference.
Given the function, <em>f(x) = 3x + 6,</em> we can solve for f(a), f(a + h) and
by substituting their values into f(x) = 3x + 6. We will have the following:

<em><u>Given:</u></em>
<em>We are told to find:</em>
- f(a)
- f(a + h), and

1. <em><u>Find f(a):</u></em>
- Substitute x = a into f(x) = 3x + 6
f(a) = 3(a) + 6
f(a) = 3a + 6
<em>2. Find f(a + h):</em>
- Substitute x = a + h into f(x) = 3x + 6
f(a + h) = 3(a + h) + 6
f(a + h) = 3a + 3h + 6
<em>3. Find </em>
<em>:</em>
- Plug in the values of f(a + h) and f(a) into

Thus:


Therefore, given the function, <em>f(x) = 3x + 6,</em> we can solve for f(a), f(a + h) and
by substituting their values into f(x) = 3x + 6. We will have the following:

Answer is C
I think you want to prove that a rectangle is a quadrilateral. You can prove this with definitions. The definition of a quadrilateral is that it is a shape with four sides. Since a rectangle has four sides, that proves that a rectangle is a quadrilateral.
