Answer 1

The domain for the function f(x) = |x + 1| is the set of all real numbers.

The range of the function is the set of positive real numbers.

Given the function f(x) = |x + 1|

f(-4) = |-4 + 1| = | -3| = 3

This means that the number -4 is at a distance of 3 units away from -1 on the number line.

f(2) = |2 + 1| = |3| = 3

This means that the number 2 is at a distance of 3 units away from -1 on the number line.

f(1.5) = |1.5 + 1| = |2.5| = 2.5

This means that the number 1.5 is at a distance of 2.5 units away from -1 on the number line.
