This is the equation in the form
so this is a linear function.
2. 
can be rewritten as
This is the equation in the form
so this is a linear function.
3. 
This function is equivalent to the function
This is quadratic, not linear function.
4. 
This is the equation in the form
so this is a linear function.
5. 
This is not linear function, because x is in the denominator.
6. 
This is not linear function because there is a squer root of x.
X²+10=9
x²=9-10
x²= -1
x =√ -1
x=i (imagnary number)
Answer is A no real number
Answer:
Step-by-step explanation:
