Which of the functions and is not linear.
The function is not a linear function.
In a linear function, each input value has a unique output value. In other words, for each point in domain, there is a unique value in the range of function. It can be written as , where m and b are real numbers.
The given functions are:
The given function is in the form of , where both m=2 and b=4 are real values. So, the function is a linear function.
The given function is a constant function and a constant function is always a linear function. So, the function is a linear function.
The given function is not a linear function because the exponent of is other than 1.
Thus, the function is not a linear function.
