Question

Find the range of f(x) =2x-6 for the domain (-2,1,5,8)

Answer 1

Answer: range: (-10,-4,4,10)

Step-by-step explanation:  range is y value and domain is x value

f(x) will be ur y

in place  of x put the value of domain

example:

1. f(x) =2x-6

             y=2(-2)-6

           = -10

2) y=2[1]-6

     = -4

like that do the rest of the working to find ur range.

Answer 2

Answer:

the range is : (-10,-4,4,10)

Step-by-step explanation:

calculate :

f(-2) = 2(-2) -6 = -10

f(1) = 2(1) -6 = -4

f(5) = 2(5) -6 = 4

f(8) = 2(8) -6 = 10

the range is : (-10,-4,4,10)
