Tell whether the function is linear. Then evaluate the function for the given value of x.
6.) f(x)= 33x; f(2)
7.) f(x)=  x+2  ; f(4)
8.) f(x)= 2/x2; f(6)
14.) f(x)=2/3x5 ; f(9)
Can someone help me with these^^. please write the QUESTION # SO I know which one the answer refers to. Merci.

6, linear, 3 6 = 3
7, V shaped, not linear 4+2 = 2 but 2 = +2
8, certainly not linear, infinite (undefined) at x = 2 !!! You had to ask me that ????
2 /(62) = 1/2
14, same sort of problem as 8
