Answer:
Step-by-step explanation:
(3,5) , (4,8) , (x,y)
if u cant see the x coordinate, then u cant tell if it is a function.
A function CANNOT have repeating x values...they can have repeating y values, just not the x ones.
Therefore, if u could see x, u would know right away if it was a function....but if u can only see y....well....thats not enough.
just so you know....the only way those 3 coordinate pairs could be a function, would be if x was any other number besides 3 or 4......because if x was 3 or 4, u would have repeating x values
A y=sin x maybe I am sorry
Consider the factors of 40: ±1, ±4, ±10, ±5, ±8 ... ±5 and <span>±8 can be manipulated to fit your factorization.
(x - 8)(x - 5) works. -8 - 5 = -13, which is what you need in the middle, and -8*-5 gives you a positive 40.</span>
