Hello! I'm just going to post the questions and then a picture with the question and answer choices.

4. Which of the following functions has a rate of change that stays the same?

5.How many real number solutions does the equation have?

6. How many real number solutions does the equation have?

7. Graph the set of points. Which model is most appropriate for the set?
(sorry if you cant see well, had to zoom out to get all of it.)

8. What type of equation will best fit the data below?

This is Unit 4 Lesson 10 Quadratic Functions and Equations Unit Test.

All help is appreciated! ;c

your answer is b ^w^ hope i

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
