Identify the domain in the function:
(1, 4) (5, 8) (-2, 5) (-3, 6) (9, 10)
x-values: 1, 5, -2, -3, 9
Is the set of ordered pair a function? Why or why not.
(-1, 4)(-3, 6)(-5, 8)(-7, 10)
Yes, the x-values don't repeat
Function or not a function:
Function: passes VLT
Linear or nonlinear? If linear identify the slope, if not why?
y=3x-8
Linear, m = 3
What is the rate of change in the equation:
-2/3x+5
-2/3
Identify the range in the set of ordered pairs:
(-1, 4)(-3, 7)(8, 9)(2, -8)(1, 5)(3, 6)
y-values: 4, 7, 9, -8, 5, 6
Does the table represent a function? Why or why not.
Yes, no x-values repeat
Function or not a function
Not a Function: Fails VLT
Linear or nonlinear? If linear identify the slope, if not why?
y = x^4+5
Nonlinear, has an exponent of 4
Calculate the rate of change between the points (2, 7) and (9, 5). Keep as a fraction.
m =-2/7
What are the other two names for the domains?
x-values and inputs
Is the mapping a function, why or why not.
Yes, no inputs are mapped to 2 outputs
Is the relation below a function and why?
No, has a vertical line and fails the VLT
Is the table linear or nonlinear, if linear state the slope, if not why.
No, the distance does not change at a constant rate.
Find the rate of change in the table
m = 1
In the function below, what is the output when the input is x = 3.
y=-3x+2
-3(3) + 2 = -7
Does the mapping represent a function?
No, the 7 is mapped to the 1 and 4
Is the relation below a function? Why?
Yes, passes the VLT
Linear or nonlinear. Explain why.
Linear, has a slope of 2
What is the average rate of change in the graph below?
m = -3/2
In the function below, what is the output when the input is x =-4?
y=x^2-7
(-4)^2-7=9
Which set of ordered pairs represents a function
I and III
Function or not a function? Why?
No, fails the VLT
Is the equation linear or nonlinear? Why?
y=abs(2x-6)
Nonlinear, has an absolute value.
Is the function increasing or decreasing from x = 1 to x = 7?
Increasing, positive slope
