if the linear function y=-2x+10 has a domain given by [-1, 4] then which of the following is its range?

Verified Answer :

(-1،12 )
(4،2 )This is the range for each of them

Answer:

\([2, 12]\)

Step-by-step explanation:

The given function is

\(y=-2x+10\)

Which domain is defined as \([-1, 4]\).

To find the corresponding range to this domain, we just have to replace the limits of the domain, and the result will be the limits of the range.

For \(x=-1\), we have

\(y=-2(-1)+10\\y=2+10=12\)

For \(x=4\), we have

\(y=-2(4)+10\\y=-8+10\\y=2\)

Therefore, the range is \([2, 12]\)
