Question

Linear
Is the function linear or nonlinear?
y = 3x² - 4x + 2
Nonlinear

Answer 1

nonlinear

Explanation:

What makes a function linear? There is only one kind of equation that produces a linear function, and it has the form

y=mx+b, where m and b are constants. Examples of this are: y=2x+3 and y=−4.

All other functions where x has an exponent that is higher than 1, e.g.
`x^(2)`,
`x^(3)`and so on, are nonlinear functions
