The document contains multiple choice questions about functions and equations. It asks the reader to identify sums, differences, principles, profit calculations, function comparisons, function evaluations, ranges, and compositions of functions. The correct answers are provided at the end.

1. Chapter 8.1 David Fanjoy, Melina Brunner, Avalon Harris, Paige Johnson, Kathryne Forbes

2. What is the sum of these two equations?f(x)=5x + g(x)=x+7 H(x)= 6x+7 H(x)=6x2+7 H(x)=5x2+7 H(x)=5x2+ 35x

3. What is the difference of these two equations? F(x)=x2+3x – g(x)=4x H(x)= x2+7x H(x)=x2-x H(x)=7x+7 H(x)=4x+12x

4. The ________states that the sum of multiple functionscan be found by adding the y-coordinates of the functions at the x-coordinate The Subposition Principle The Supposition Principle The Ordinate Principle The Superposition Principle

8. For the functions f(x)=2x2-4 and g(x)=x3What is f(4) – g(3)? -1 0 1 2

9. What is the range of f(x) +g(x) when f(x)=2x+4 and g(x)=-2x-4? Y=4 Y=2 Y=0 Y=8

10. If h(x)=f(x)+g(x) and f(x)=4x+2 and g(x)=x+3What is h(4)? 15 24 29 31
