For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}
  R:{1, -3, -4}

• Not a Function

Which graph is not a function?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled.

Select the true statement below.

• The total capacity of the water tank is 2000 gallons.

• The total capacity of the water tank is 400 gallons.

• The rate of change for the graph is 300 gallons per hour.

• The rate of change for the graph is $-\frac{2}{5}$ .

Is this table a function?  Why?

• Yes, because none of the inputs repeat.

• Yes, because the inputs repeat but have the same output.

• No, because the inputs repeat and have different outputs.

What are the x- intercepts?

• x= 0 and x= -4

• x= 0 and x= 4

• y= 0

• x= 2

Solve
4m² - 100 = 0

• m=25, -25

• m=96

• m=5, -5

• m=-96
