a.0<=y<=8

b.0<=y<00(infinity)

C2<=y<=6

d.-00

the answer is (a) 0<=y<=8. because 2(2)-4=0 and 2(6)-4=8.

Cetacea

The range is a. \(0\le y\le8\).

Given that the domain is \(2\le x\le6\).

For x = 2, f(x) = f(2) = 2(2) - 4 = 0.

For x = 6, f(x) = f(6) = 2(6) - 4= 8.

It means the range is \(0\le y\le8\).
