Tell whether the function is linear. Then evaluate the function for the given value of x.



6.) f(x)= 3-3x; f(2)

7.) f(x)= | x+2 | ; f(-4)

8.) f(x)= 2/x-2; f(6)

14.) f(x)=2/3x-5 ; 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 /(6-2) = 1/2

14, same sort of problem as 8
