Algebra 1 help
5. Which set of ordered pairs represent y as a function of x? A. {(-9, 2), (0, 6), (1, -2), (-3, 6)} B. {(-1, 0), (4, 3), (-7, -3) (-1, -8)} C. {(3, 2), (-4, -2), (3, 1), (-4, 1)} D. {(5, 4), (2, 3), (1, 1), (2, 4)} http://prntscr.com/7abeva
you the ndefinitio of the function?
what do you mean? yes. is my original answer (c) right?
no
a set of ordered pairs represent a function if there are two such pairs that (a,b) and (a,c), it holds that b=c
I don't get this. This is like my first time doing algebra opposed to geometry so I'm new
obviously in c) it doesn't hold, since thete are pairs (3,2) and (3,1). Same first number, different second one. So it is not a function
don't get it
imagine that the two numbers of each pair, represent the x and y of some function. So what can not happen is that same x has two or more y asigned to it. Because then the definition is not consistent
Ohhh ok A lol
right
can you help me with a few more I didn't get?
post a new question
As a thread? wouldn't that be spammy
