Mathematics: Let f be a function such that f(x)=2x-4 is defined on the domain.2 is less than or equal to x and x is lss than or equal to 6. the range of the function is a) 0 is less thanor equal to and y is less than or equal to 8 b)0 is less than or equal to y and is less than infinity c)2 is less than or equal to y andy is less than or equal to 6 d)negative infinity is less than y and y is less than infinity

It is going to be linear the slope is -2 and the y-intercept is -2...

Option A.

Step-by-step explanation:

The given function is

f(x)=2x-4

It is defined on the domain $2\leq x\leq 6$ .

We need to find the range.

Range is the set of output values.

$2\leq x\leq 6$

Multiply 2 on each side.

$4\leq 2x\leq 12$

Subtract 4 from each side.

$4-4\leq 2x-4\leq 12-4$

$0\leq f(x)\leq 8$

$0\leq y\leq 8$

The range of the function is $0\leq y\leq 8$ .

Therefore, the correct option is A.
