Question

Which equation represents a linear function? A) y = |x| B) y = x2 C) y = -3x3 D) y = 1 4 x

Answer 1

D hope that helps good luck

Answer 2

Linear means the highest exponent on the placholder is 1
it is also just a straight line

y=|x| is like y=(√x)², it is 2 straight lines

B. y=x², exponent is 2 so no

C. y=-3x³, exponent is 3, so no

D. y=1/4x, yep


D is the answer
