Question

The set of ordered pairs (-1, 8), (0, 3), (1, -2), and (2-7) represent a function. What is the range of the function?

{x x=-1, 0, 1, 2}

{y_y=-7, -2, 3, 8}

O {x x=-7, -2,-1, 0, 1, 2, 3, 8}

O {y y=-7, -2, -1, 0, 1, 2, 3, 8}

Answer 1

b) {y=-7,-2,3,8}

Explanation:

Since the points (1,-8),(0,3),(1,-2), and (2,-7) represent a function, then first component of the ordered point (a,b) represents the value of the independent variable of the function, and the second component represents the value of the function evaluated in the first component.

Since the range of the function correspon to the set of values that the function takes in points of the domain then, the range is the set of second components of the ordered pairs, that is {y=-7,-2,3,8}
