+4 We are talking about linear and nonlinear in class and I don't get it
+128407 Linear : implies a variable - usually x - raised to the first power
So y = x + 3 is a linear graph [ graph of a straight line ]
Non- linear...... x raised to some other power
So y = x^2 is a non-linear [ curved graph ]
