Question

Is f(x)=-6x+6 a linear function?

Answer 1

Since the function is in the form f(x) = mx+b where m = -6 and b = 6, this means that the function is linear.

Answer 2

Visually, the function plots a straight line on a graph. So this shows us that the function is linear.

Answer 3

but i dont understand what to look for in the mx+b. whats an example of one that isn't a linear function?

Answer 4

\[\text{ $f(x) = x^2$ is an example of a nonlinear function. }\]
