Answer 1

Answer: y = 2x³ + 1 . non-linear

y = 3x . linear

y = x/5 linear

Explanation:

The attachment shows graphs of the three equations. If the line is straight, the equation is linear. If it curves, it is not linear.

Equations with exponents are not linear.

Answer 2

Attached picture below.

1.) y=2x^3+1 answer: nonlinear

2.) y=3x answer: linear

3.) y=(x/5) answer: linear
