Due today will give no one has me is each function linear or nonlinear? y= 2^2 − 5x y= x/3 y= x^3 + 1/3

Y=5x-4 is linear

y=x/3 is linear

y=x^3+1/3 is non linear

Basically linear means it is a straight line when graphed. So anything with exponts is non linear by default among some other rules for determining linear or nonlinear  Hope this helps! Please rate my answer and help me also! Thank YOU:)

y= 2^2 − 5x is linear.  2^2 is just a constant.  The x in 5x has the power 1.

y = x/3 is linear.  Think of it as y = (1/3)x.  Again, we have the 1st power of x.

y = x^3 + 1/3 is nonlinear.  It's a cubic.  Note the 3rd power of x.

Istg idk..if there all the same length there all the same number but use google
