Answer:
y=x^3/3
; x=3
; y= √x-3
; and y= | x+3 |
.
Step-by-step explanation:
In a linear function, we have both a y, an x, and the highest power of each is 1.
In the first function, x has a power of 3; this means it is nonlinear.
In the second function, both y and x have a power of 1; this means it is linear.
In the third function, there is no y; it is an x = c equation, which makes it a vertical line and thus not a function. This means it is not a linear function.
In the fourth function, we have a square root; this means the power of x is 1/2, not 1, and the function is not linear.
In the fifth function, we have absolute value bars. This means it is an absolute value function and not a linear function.
In the sixth function, both x and y have a power of 1; this means it is linear.
