Question

For what values of x, does the graph's slope equal zero?​

Answer 1

1 < x ≤ 2

Explanation:

A graph's slope equals zero when there is a change in the x-value, but there's no change in the y-value.

Here, we can see in the piecewise function that between 1 (not included) and 2 (included), the slope of the graph is 0.

Therefore, 1 < x ≤ 2 is correct
