Question

Let f(x)=-5x-4 and g(x)=6x-7. find f(x) + g(x)

Answer 1

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!

Step-by-step explanation:

Answer 2

F(x) = -5x - 4

g(x) = 6x - 7

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

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