Question

Use the greatest integer function shown in the following graph to find the value of y when x=−1.5 . (1 point) Responses y=−0.5 y = - 0 . 5 y=−1 y = - 1 y=−1.5 y = - 1 . 5 y=−2

Answer 1

The greatest integer function, also known as the floor function, is defined as the greatest integer less than or equal to a given number.

For \( x = -1.5 \):
- The greatest integer less than or equal to \(-1.5\) is \(-2\).

Thus, when \( x = -1.5 \), \( y = -2 \).

So, the correct response is \( y = -2 \).
