Answer:
the relation is not one-to-one.
Step-by-step explanation:
it can't because every number is in the 4th quadrant.
Step-by-step explanation:
g. (1/4 + 1/2) = 3/4
3/4 ÷ 3/2 = 1/2
h. (1/5 - 1/2) = 3/10
3/10 ÷ 3/5 = 1/2
I. (2/5 ÷ 5/6) = 12/25
12/25 × 7/8 = 21/50
(4-x) /(3x+21)
The denominator cannot be zero
3x + 21 ≠ 0
3x ≠ -21
x ≠ -7
The domain of the function will be all real number except -7
{x | x ≠ -7}
