To estimate, round first then do the math. If you round 5,397 to 5400 and 62 rounds to 60, then 5400÷60 = 90.
90 is the BEST estimate.
Answer:
It is a relation and a function.
Step-by-step explanation:
The expression: is a relation because it connects x values of the Real number set with y values of the Real number set via this associated equation.
It is also a function,because this relation satisfies that for each x-value in the starting set called Domain (which in this case is as we said the Real number set), there is ONLY one value in the END set (called the Range) associated it.
