what is the range of the given function? {(-2, 0), (-4, -3), (2, -9), (0, 5), (-5, 7)} {x | x = -5, -4, -2, 0, 2} {y | y = -9, -3, 0, 5, 7} {x | x = -9, -5, -4, -3, -2, 0, 2, 5, 7} {y | y = -9, -5, -4, -3, -2, 0, 2, 5, 7}
Answer
Explanation:
Step1: Recall range definition
The range of a function given as a set of ordered - pairs $(x,y)$ is the set of all $y$ - values.
Step2: Identify $y$ - values
In the set ${(-2,0),(-4, - 3),(2,-9),(0,5),(-5,7)}$, the $y$ - values are $0,-3,-9,5,7$.
Step3: Write the range set
The range is ${y|y = - 9,-3,0,5,7}$.
Answer:
B. ${y|y = - 9,-3,0,5,7}$
