Question

Whcih of these equations define y as a nonlinear function of x?

Select each correct answer.


A) 3y=2x-1.5

B)y=x²+3

C) 5(x+y)=-25

D) y=x³

E) y=1

F) y=12-x²

Answer 1

hello :

note :

the linear function of x have equation : y = ax + b

correct answer is : A) and C) and E)

A) : 3y = 2x -15

y = (2/3)x -15/3

y = ( 2/3)x -5 ..... when : a = 2/3 and b = -5

B) : 5(x+y)=-25

x + y = - 5

y = - x -5 ...... when : a = -1 and b = -5

C) y = 1

y = 0x +1 .....when : a = 0 and b = 1
