Question

Is this function a linear function? Yes or no y= 2x^2

Answer 1

Answer:

No

Reasoning:

There are two ways to figure this out.

1. You know when a function is linear when the equation is in the slope-intercept format. Which looks like $y=mx+b$

This does not look like that. So, it isn't a linear function.

2. Graph! If you graph the function, the graph will look like the figure below. It's not a line. This is called a parabola. Meaning, it's not a linear function.

Answer 2

Answer:

no

Step-by-step explanation:

because 2x is squared you know it will be curved as it is always with squared numbers or variables in a function
