Do you think that the equation y= 2x cubed is a linear function? Why or why not.

Question

you have to times 2 by itself twice like 2times2times2

Answer 1

The equation you posted above is not a linear function.  It's a cubic function.

 

y = (2x)³

Cubic refers to the exponent which is 3 in this case.

 

A linear function would be of the form y = mx + b, where m is the slope of the line and b is the y-intercept.  Notice there are no exponents in a linear function.

Answer 2

A linear function is of degree 1, e.g., y = 2x - 3.

y = 2x³ is of degree 3. It is not a linear function.
