Functions Intro 20
What is the domain of the given function?
{x | x = -6, -1, 0, 3}
What is the domain of the function shown in the mapping?
{x | x = -5, -3, 1, 2, 6}
Which explains why the graph is not a function?
It is not a function because there are two different y-values for a single x-value.
Which ordered pair could be removed from the graph to create a set of ordered pairs that represents a function?
(1, 3)
The table shows ordered pairs of the function y = 8 - 2x. When x = 8, the value of y is
-8
What is the lowest value of the range of the function shown on the graph?
2
How many points need to be removed from this graph so that it will be a function?
3 points
What is the domain of the function on the graph?
all real numbers greater than or equal to -3
What is the range of the function on the graph?
all real numbers greater than or equal to 2
Which set of ordered pairs represents a function?
{(3, -1), (7, 1), (-6, -1), (9, 1), (2, -1)}
What is the domain of the given function? {(3, -2), (6, 1), (-1, 4), (5, 9), (-4, 0)}
{x | x = -4, -1, 3, 5, 6}
Livia eats a chicken drumstick with 11 grams of protein. She also eats x cheese sticks, each with 7 grams of protein. The table shows y , the total number of grams of protein that Livia will consume if she eats x cheese sticks. What is the range of the function?
all real numbers greater than or equal to 11
Raj's bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining. What is the range of this function?
all real numbers such that 0 ≤ y ≤ 40
What is the range of the function on the graph?
all real numbers less than or equal to 3
What is the range of the function on the graph?
all the real numbers greater than or equal to -3
What is the range of the given function?
{y | y = -7, -1, 0, 9}
What is the range of the given function? {(-2, 0), (-4, -3), (2, -9), (0, 5), (-5, 7)}
{y | y = -9, -3, 0, 5, 7}
