Question

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 1

The range of a function is the set of all possible y-values the function takes.

We have the function:

$\left\{\left(-2,0\right),(-4,-3),(2,-9),(0,5),(-5,7)\right\}$

Then, the range is:

$Ran={}\lbrace y|y=-9,-3,0,5,7\rbrace$
