determine if function is linear
How do you find out if a function is linear?
A linear function refers to when the dependent variable (usually expressed by 'y') changes by a constant amount as the independent variable (usually 'x') also changes by a constant amount.
For example, the number of times the second hand on a clock ticks over time, is a linear function.How do you determine if an equation is nonlinear or linear?
Yes, the general rule is that if an equation can be written in the form y=mx+b, where m and b are constants, then the equation is linear.
If the equation cannot be written in this form, then it is nonlinear.How do you prove a linear function is linear?
A linear function must satisfy f(cx)=cf(x) for any number c.
The other requirement for a linear function is that applying f to the sum of two inputs x and y is the same thing as adding the results from being applied to the inputs individually, i.e., f(x+y)=f(x)+f(y).If the variable is not in the exponent, then it is a quadratic equation.
If the function does not have an exponent, then it is a linear function.
