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

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
