Answer:
Linear function : [tex]y=\frac{x}{2}-19,13y=\frac{1}{3}x+5, y=x+\frac{25}{5}[/tex]
Non - Linear function : [tex]3y=x^2, y^3=x[/tex]
Step-by-step explanation:
Linear function : If a function has either one or two variables with degree 1, then it is known as linear function. The graph of a linear function is always a straight line.
Non - Linear function : If a function has either one or two variables with exponents, then it is known as non-linear function. The graph of a non-linear function is a curve.
[tex]y=\frac{x}{2}-19[/tex]
Here, degree of both variables is 1. So, it is a linear function.
[tex]3y=x^2[/tex]
Here, degree of y is 1 and degree of x is 2. So, it is a non-linear function.
[tex]13y=\frac{1}{3}x+5[/tex]
Here, degree of both variables is 1. So, it is a linear function.
[tex]y=x+\frac{25}{5}[/tex]
Here, degree of both variables is 1. So, it is a linear function.
[tex]y^3=x[/tex]
Here, degree of y is 3 and degree of x is 1. So, it is a non-linear function.
