Answer:

1. (2), (4), (5)

2. (4l

3. (3)

4. (2)

5. (1)

Explanation:

1.

g(0) = 0

g(-1) = 1

g(1) = 1

2.

since q is the independent variable s must be dependent on q and hence s must be equal to f(q)

6q = 3s - 9

3s = 6q + 9

s = 2q + 3

f(q) = 2q + 3

that is the last option

3.

= 1

4.

= -1

5.

= -8

Answer:

#1: (B, D, E)

#2: (D) f(q) = 2q + 3

#3: (C) 1

#4: (B) f(5) = -1

#5: (A) - 8

Explanation:

Question 1:

The number inside the parentheses is the input value, or x coordinate, and the output value (the number on the right side of the equal sign) is the y coordinate.

Use basic graph plotting skills to see if the x coordinate has a y coordinate value that's ON the graph line.

Question 2:

The variable "q" is our independent variable, also known as our x variable if you used the y = mx + b formula.

To rewrite 6q = 3s - 9 into function notation, you would solve for variable "s" using basic algebra:

6q = 3s - 9

6q + 9 = 3s

2q + 3 = s

s = 2q + 3 or f(q) = 2q + 3

Question 3:

The number inside the parentheses, -2, is the input value, or the x coordinate. Looking at the table, you can see that when you input -2, you get an ouput of 1.

Question 4:

Use the same process as Question 1.

Question 5:

The number inside the parentheses, 5, is the input value, or the x coordinate. Looking at the table, you can see that when you input 5, you get an ouput of -8.

Hope it helps (●'◡'●)
