Question 915795:  Which of the following are polynomials? If the function is a polynomial, give the degree and the leading  
coefficient (LC). If the function is not a polynomial, give a polynomial property that it fails to have.  
(For each function write Polynomial?  
i. f(x) = π – x/4  
ii. g(x ) = 3^x  
iii. h(x) = (2x + 6)(x – 3)^2 ( x + 1)^3 
 
please explain why, 
Thank you

You can  put this solution on YOUR website! Which of the following are polynomials? If the function is a polynomial, give the degree and the leading coefficient (LC). If the function is not a polynomial, give a polynomial property that it fails to have.  
(For each function write Polynomial?  
i. f(x) = π – x/4:::: Is a polynomial::: LC = -1/4 
---------------------------------  
ii. g(x ) = 3^x::: Is not a polynomial::: variable is an exponent 
----------------------------------  
iii. h(x) = (2x + 6)(x – 3)^2 ( x + 1)^3 ::: Is a polynomial::: 
h(x) = (2x+6)(x^2-6x+9)(x^3 etc) 
Highest power term =  2x*x^2*x^3 = 2x^6 
LC = 2
