Over what interval is the function of the graph

1 ≤ x ≤ 6                             Option A

Step-by-step explanation:

When graph is constant it means, value of graph ( y-values)  not to be change different values of x in given interval.

In other words, graph must be parallel to the x axis is known as the constant graph.

A function is a measure of the rate of change of function values with respect to change in input values.

In given graph horizontal line is lie on the interval from x ≥ 1 to x ≤ 6.

So, option A is correct.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
