What is the range of the given function?

a.{x | x = –5, 1, 4, 6}

b.{y | y = –7, –1, 0, 9}
c.{x | x = –7, –5, –1, 0, 1, 4, 6, 9}
d.{y | y = –7, –5, –1, 0, 1, 4, 6, 9}

we know that

The Domain of the function are all the values of x that can take the function

in this problem the domain is

The Range of the function are all the values of y that can take the function

in this problem the range is

therefore

the answer is the option

B.{y | y = –7, –1, 0, 9}
