Which functions are nonlinear? select all that apply. a. y=-3x b. y=6x^2 c. y=x-2 d. y=1/x+4 e. y=4x+5

Linear functions are functions that graph to form a straight line. This means that options B and D are not linear, as B is a quadratic and therefore would graph as a quadratic curve, and D is reciprocal and therefore wouldn't be a straight line, so those are the ones you should select.
I hope this helps!

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
