**Answer:**

It is A, C, and D the only incorrect answer is B

**Step-by-step explanation:**

**Answer:**

One other zero of f(x) is (3+6i)

**Step-by-step explanation:**

we know that

The <u>Conjugate Zeros Theorem</u> states that if a complex number a + bi is a zero of a polynomial with real coefficients then the complex conjugate of that number, which is a - bi, is also a zero of the polynomial

In this problem we have

Is a polynomial with real coefficients

so

If (3-6i) is a zero of f(x)

then

The complex conjugate of that number, is also a zero of the polynomial

The complex conjugate is (3+6i)

therefore

One other zero of f(x) is (3+6i)

The general form for a straight line is y = mx + c where m is slope and c is y-intercept.

Two lines are perpendicular when the product of their slopes = -1

Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2

So a line perpendicular to the given and has the same y-intercept is

y = (-7/3) x - 2

**Answer:**

**A. The elements in the domain of f(x) for which g(f(x)) is defined**

I just took the test myself. (gºf)(x) can be rewritten as g(f(x)) and the interior function, which is f(x) in this case, is the domain, where x is defined.

What's the rest?You only said, From 180 books to 150 books sooo you gotta put the rest or nobody will answer it.
