Question

If the domain of a function that is translated down 3 is (0, 4), (-5, 8), (4, -2), what is the range?

Answer 1

Given:

The domain of function that is translated down 3 is (0, 4), (-5, 8), (4, -2).

To find:

The range of the function.

Solution:

If a function is translated 3 units down, then

$(x,y)\to (x,y-3)$

Using this rule, we get

$(0,4)\to (0,4-3)$

$(0,4)\to (0,1)$

Similarly,

$(-5,8)\to (-5,5)$

$(4,-2)\to (4,-5)$

The range of the given function is (0, 1), (-5, 5), (4, -5).

Therefore, the correct option is A.
