Answer:Unit 2 Lesson 6 Function Operations

1. D x - 11

2. B -3x + 9 Don't get confused with the - 7, since you are subtracting 3x + 2 - 6x - 7, the - 7 switches to + 7.

3. C -30x^2 + 28x - 6; all real numbers

4. D x - 4; all real numbers except x /= -4

5. C It doesn't matter which discount is applied first, the result will be the same.

100% correct, cheers!

F(x) = -5x - 4

g(x) = 6x - 7

f(x) + g(x) = (-5x-4) + (6x-7)

f(x) + g(x) = x - 11

If 2 + 5i is a zero, then by the complex conjugate root theorem, we must have its conjugate as a zero to have a polynomial containing real coefficients. Therefore, the zeros are -3, 2 + 5i, and 2 - 5i. We have three zeros so this is a degree 3 polynomial (n = 3).
f(x) has the equation
f(x) = (x+3)(x - (2 + 5i))(x - (2 - 5i))
If we expand this polynomial out, we get the simplest standard form
f(x) = x^3-x^2+17x+87
Therefore the answer to this question is f(x) = x^3-x^2+17x+87
