What is the range of the function {(0, 15), (4, 6), (6, 4), (8, 0)}?

lana66690 [7]

The range of a function is the set of output values of the function

The range of the function is: {15, 6, 4, 0}

<h3>How to determine the range</h3>

The function is defined as:

(x,y) = {(0, 15), (4, 6), (6, 4), (8, 0)}

The range is the y-values.

So, we have:

y = {15, 6, 4, 0}

Hence, the range of the function is: {15, 6, 4, 0}
