Question

the table compares the capacity of omojobis phones battery when he started charging it (in percentage points) and the time it took the battery to be fully charged (in minutes), for several different occasions. can the time it takes to fully charge the battery be represented as a function of the batterys capacity when the charging begins? initial capacity (percentage points) time to charge (minutes) 65 20 40 30 30 34 45 27 65 18 10 40 30 32 25 36 choose 1 answer: a yes b no

Explanation:

To determine if time is a function of initial capacity, we check the definition of a function: each input (initial capacity) must have exactly one output (time to charge).

Step1: Check input 65

Initial capacity 65 has times 20 and 18. Different outputs for the same input.

Step2: Check input 30

Initial capacity 30 has times 34 and 32. Different outputs for the same input.
Since there are inputs with multiple outputs, time is not a function of initial capacity.

Answer:

B. No
