Which Function Is It?

Example 1 Is 3x + 4 = 2y linear or quadratic?

Since the degree of the function is one, the equation is linear. In standard form the equation is 3x - 2y = -4.

Example 2 Is 4x - 3y = 2x² linear or quadratic?

Since the degree of the function is two, the equation is quadratic. In standard form the equation is .
