Question

Over what interval is the function in this graph constant? A. 65*10 B, 1 sxs6 C. -4 sxs1 D. -10 5-4 ​

Answer 1

Given:

The graph of a function.

To find:

The interval at which the graph of the function is a constant.

Solution:

From the given graph it is clear that the graph is a horizontal line and parallel to the x-axis over the interval
`1\leq x\leq 6`.

Over the interval
`1\leq x\leq 6`, the value of the function is constant, i.e., y=7.

It means the graph of the function is constant over the interval [1,6].

Therefore, the correct option is B.
