Question

Determine if each function is linear or nonlinear.

A= linear B=non-linear

3x+y=12 A or B
y= \frac{6}{y} -2 A or B
y= \frac{x}{2} -3 A or B
y=3 x^{3} +5 A or B
y=x A or B

Answer 1

linear simply means the higest power of any placeholder is 1 and positive

first one, all 1, linear, A

2nd one
that is actually 6y^-1, that is negative exponent so not linear, so B

3rd one: correct, that is just x^1 times 1/2 minus 3 so linear, so A

4th one, x^3, duh, not 1, non-linear, B

5th one, fist degree, linear, A
