question What is the domain of the function shown in the mapping?
{x | x = -5, -3, 1, 2, 6}
question
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}
question What is the domain of the given function?
{x | x = -6, -1, 0, 3}
question
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
question
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
question What is the domain of the function on the graph?
all real numbers greater than or equal to -3
question What is the range of the function on the graph?
all the real numbers greater than or equal to -3
question What is the range of the function on the graph?
all real numbers greater than or equal to 2
question
Which set of ordered pairs represents a function?
{(3, -1), (7, 1), (-6, -1), (9, 1), (2, -1)}
question Which ordered pair could be removed from the graph to create a set of ordered pairs that represents a function?
(1, 3)
question 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.
question What is the lowest value of the range of the function shown on the graph?
2
question The table shows ordered pairs of the function y = 8 - 2x. When x = 8, the value of y is
-8
question
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}
question What is the range of the given function?
