Question

Y=7-4x; domain={-3,-1,5}
I have to find the range
PLS HELP ASAP

Answer 1

range { - 13, 11, 19 }

Explanation:

To find the range ( output) substitute values from the domain (input ) into y

x = - 3 : y = 7 - 4(- 3) = 7 + 12 = 19

x = - 1 : y = 7 - 4(- 1) = 7 + 4 = 11

x = 5 : y = 7 - 4(5) = 7 - 20 = - 13

range { - 13, 11, 19 }
