Where is the function fx=x2increasing? Where is it decreasing?

Short Answer

Expert verified

The given function increase in interval0,鈭� and decrease in interval-鈭�,0

Step by step solution

01

Step 1. Definition

If the value of fxis increasing on increasing the value of x, then the function is known as an increasing function

If the value of role="math" localid="1646841555914" fx is decreasing on increasing the value of x, then the function is known as a decreasing function.

02

Step 2. Explanation

If we put any value of xbetween -鈭�,0the value of ydecrease and we put any value of xbetween 0,鈭�the value of yincrease

So, given function increase in interval0,鈭� and decrease in interval-鈭�,0.
