Answer:

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

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)

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.
