Question

I REALLY struggle with it !!!

Answer 1

what is your question?

Answer 2

The point (1, -5) is an ordered pair for which function? so i did some work but i keep on getting the wrong one not from the choices provided

Answer 3

just substitute -5 for y and 1 for x in your equations and check which one will be correct.

Answer 4

yeah i already substitude -5 and 1 i'll tell you what i'll get

Answer 5

what are your choices anyways?

Answer 6

if you wanna see 'em here :)
ƒ(x ) = 3x - 11
ƒ(x ) = 2x - 7
ƒ(x ) = -x + 9

Answer 7

ok so it will look like:

-5=3-11
-5=-8 wrong


-5=2-7
-5=-5 correct

-5=1+9
-5=10 wrong

Answer 8

i see but then what do i do with 1??

Answer 9

you substitute 1 instead of x,

Answer 10

yeah i did substitute and I had this ƒ(x) = 5(1) + 5

Answer 11

wait:
ƒ(x ) = 3x - 11
-5=3*1-11
-5=-8 wrong


ƒ(x ) = 2x - 7
-5=2*1-7
-5=-5 correct


ƒ(x ) = -x + 9
-5=1+9
-5=10 wrong
