Where is the function increasing?
A)1 B)3< X C)-infinity < x < 1
D)-infinity

A)

Step-by-step explanation:

Given:

A graph of a function.

When we analyze the given graph, it is of a parabola.

To find:

The interval of values of where the function is increasing.

Solution:

First of all, let us learn about the meaning of increasing and decreasing functions.

1. A function is known as increasing  in an interval when

Value of y keeps on increasing when we move from the value of x from a to b.

2. A function is known as decreasing  in an interval when

Value of y keeps on decreasing when we move from the value of x from a to b.

On analyzing the given graph , we can see that the graph is decreasing on the interval:

and is increasing on the interval:

When we choose from the options,

The correct answer is option A)
