Question

2. Cross out the equations that are NOT linear functions.

y = 3x+2
y = 3/x
y = -2
y=4
y = x2(square) + 5

Answer 1

Y=4 is the correct I think

Answer 2

Welcome to the concept of the maths.

Here, we can see, that Linear equation always have highest power or degree of its variable as '1' ,

thus here, y = 3/x has degree as -1 and y = x^2 +5 has degree 2 ,

hence,

The equations that are NOT linear are

2.) y = 3/x and 5.) y = x^2 + 5
