Question

The graph of a function is shown below. What is the range?

A.) {1,2,3,4}
B.) All Real Numbers
C.) {1,2,4}
D.) {1,2,3,5}

Answer 1

C) {1, 2, 4}

Explanation:

The coordinates of the point (x, y).

x is in the DOMAIN

y is in the RANGE

From the graph we have the points

(1, 2) → x = 1, y = 2

(2, 1) → x = 2, y = 1

(3, 4) → x = 3, y = 4

(5, 2) → x = 5, y = 2

DOMAIN = {1, 2, 3, 5}

RANGE = { 1, 2, 4}

/we only take the repeating element once/
