C. Determine whether each rule below represents a function or not. Write F if it's a function and R if its not a function:

5.
[tex]y = 3x + 9[/tex]


6.
[tex]y = - 2x - 7[/tex]

7.
[tex]x + y = 10[/tex]

8.
[tex]x {}^{2} + y = 2[/tex]

9.
[tex]2x {}^{2} + y {}^{2} = 8[/tex]


P.S need ko na po ngayon...


Salamat po...
