The input value is the x value, and the output value is the y value.
You know y = 5, so you can plug it into the function to find the input:
y = x - 3 Plug in 5 for y
5 = x - 3 Add 3 on both sides
5 + 3 = x - 3 + 3
8 = x
Answer:
8
Step-by-step explanation:
y= x -3
to get the Anwer I got i Subtracted
Because the output value is supposed to be five so?
5= x-3
Well 2 does get 5 if you add 2+ 3 together!
but if you subtract 3 -2 you get 1..
and 5 - 3 = 2 not 5
and adding 8 + 3 is 11 but subtracting it is 5!
which is
5= 8 - 3
