Answer:
Step-by-step explanation:
No. A function maps one input to exactly one output. The given relation maps 1 to both 1 and -1, as indicated by the pairs (1, 1) and (1, -1).
Irrational numbers are nonrepeating decimals like 0.1257486...
sqrt(150) is irrational gives nonrepeating decimal
12^2 = 144
sqrt(625) = 25
sqrt(49) .. sqrt(50) .. sqrt(64)
7 .. sqrt(50) .. 8
in between 7 and 8
It’s the heigh. Times the radius and volume
h= V/r
