Is it a Function?
100
True or False-A relation is a set of ordered pairs
What is TRUE?
100
Evaluate f(x)=-3x if x=-12
What is 36?
100
f(x) = 9 - x g(x) = 3x + 2 h(x) = |3 - x| What is f(g(2))?
What is 1?
100
The point (1,2) is in this quadrant
What is the 1st quadrant?
100
Evaluate the set of coordinate pairs. Identify if it is a function and explain why? {(2, 3), (4, 5), ( -2, 6)}
What is YES, a Function because x (the domain) does not repeat?
200
The set of first coordinates of a relation or a function
What is Domain (also the x value)?
200
Evaluate f(x)=2x+1 if x=-2
What is -3?
200
f(x) = 9 - x g(x) = 3x + 2 h(x) = |3 - x| What is g(f(-2))?
What is 35?
200
How do you graph the point (-3,4)?
What is you go left 3 units on the x-axis then go up 4 units on the y-axis?
200
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function? Why?
What is False, the points fail the vertical line test because there is more than 1 value for the domain (x value)
300
The set of second coordinates in a relation or a function
What is the range (also the y value)?
300
Evaluate f(x)=-3 - x if x=6
What is -9?
300
f(x) = 9 - x g(x) = 3x + 2 h(x) = |3 - x| What is h(g(1))?
What is 2?
300
The signs of the points in quadrant 2
What is the (- , +)?
300
Evaluate the set of coordinate pairs. Identify if it is a function and explain why? {(2, 3), (4, 5), (7, 5), (4, 3), ( -2, 6)}
What is NO, not a function because x value (domain) repeats?
400
A relation that assigns exactly one value in the range to each value in the domain?
What is a function?
400
Evaluate f(x)=25 + 4x if x=-5
What is 5?
400
f(x) = 9 - x g(x) = 3x + 2 h(x) = |3 - x| What is f(g(a))?
What is 7 - 3a?
400
The quadrant that doesn't contain one of these points (-2,3), (3,-4) (2,3)
What is the third quadrant?
400
Using the vertical line test does the graph of the points (-2,5), (1,8), and (5,3) represent a function? Why?
What is YES because it passes the Vertical Line Test and the domain (x) has only 1 range (y) value?
500
The test to tell if a graph is a function
What is the Vertical Line Test?
500
Evaluate f(x)=-(4x+2) if x=7
What is -30
500
f(x) = 9 - x g(x) = 3x + 2 h(x) = |3 - x| What is f(g(h(5)))?
What is 1?
500
What quadrant is the point (0,2) in?
What is none because the point sits on the y-axis
500
Is it a function?
What is NO because it does not pass the Vertical Line Test?
