Fast! : < determine if each function is linear or nonlinear. drag each function into a box to correctly classify it. y = 2x^3 y = x + 5 y = x^2 -3 5x + 5y = 25 y = x^2/2

ANSWER

The linear functions are,

and



EXPLANATION

All linear functions can be written in the form


or



From the given options the two functions that are of these forms are



and



The remaining ones are non linear because their highest degree is not 1.

Moreover, their graphs are not straight lines, meanwhile the graph of all linear functions are straight lines.
