100
The coordinate plane is divided into how many quadrants?
4
100
Is a range the set of x-values or y-values?
y-values
100
True or False? A function can have repeating x-values.
False
100
f(x) = x + 5 for x = -9
-4
200
Which axis runs left and right - the x-axis or the y-axis?
x-axis
200
Is a domain the set of x-values or y-values?
x-values
200
Is the following relation a function?
{(4, 3), (-2, 1), (-1, 3), (4, -2), (-1, 1)}
No! There are repeating x-values.
200
What is the function rule for the table shown?
y = x + 6
300
Name the ordered pair that is shown on the graph below.
(4, -2)
300
What is the domain of {(-2, 1), (3, 5), (4, 9)}?
{-2, 3, 4}
300
Is the following relation a function?
Yes! The x-values do NOT repeat (there are not 2 lines coming out of any numbers in the x column).
300
In the graph below, evaluate f(2).
1
400
Which point is plotted at (-3, -5) ... the moon, heart, star or triangle?
star
400
What is the range of {(-2, 1), (3, 5), (4, 9)}?
{1, 5, 9}
400
Is the following relation a function?
Yes! If we use the Vertical Line Test, we can pass a vertical line across the graph and it will never touch more than one point at a time.
400
If the function table below is extended, what will be the value of y when x = 7?
