Question

If the function rule is y equals 3x - 4 what is range when the domain is 7?​

Answer 1

Domain is another word for the x value. so, this question just asking us to solve for y when x = 7

first, substitute in x

y = 3(7) -4

and then solve for y

y = 21 - 4
y = 17

so, the range is 17 when the domain is 7
