Can anyone please help me !!

The second one

Step-by-step explanation:

in a function, each time an x value is shown, it needs the same output. in this, 0 has an output of -3 and -4 so it is not a function.

The lowest common denominator (LCM) is the lowest whole number divisible by both denominators without a remainder.

EASY LCM:
multiply the two denominators, then divide the total by the greatest common factor (GCF) between the two denominators.

=(64*32)/32
=2,048/32
=64

-OR-

DETAILED METHOD
STEP 1:
Find prime factors of denominators.
8/64
64: 2 x 2 x 2 x 2 x 2 x 2

8/32
32: 2 x 2 x 2 x 2 x 2

STEP 2:
If factors occur more than once, multiply them the greater number of times they occur.

2 x 2 x 2 x 2 x 2 x 2= 64

ANSWER: The LCM of 8/64 and 8/32 is 64.

Hope this helps! :)
