Step-by-Step Solution

To determine whether the function y=2x3 y = 2x - 3 is increasing or decreasing, we need to analyze the slope of the linear function.

We start by identifying the equation given: y=2x3 y = 2x - 3 .

This equation is in the standard linear form, y=mx+b y = mx + b , where:
m m is the slope, and
b b is the y-intercept.

The slope m m in this equation is 2 2 . In the context of linear functions:

  • If m > 0 , the function is increasing.

  • If m < 0 , the function is decreasing.

  • If m=0 m = 0 , the function is constant (neither increasing nor decreasing).

In our function, the slope m=2 m = 2 , which is greater than zero. Therefore, we can conclude that the function y=2x3 y = 2x - 3 is increasing.

As a result, the function is increasing.

Answer

Increasing
