Question 5

If  , find  . ​

Accepted Answer

In the first set of characters, the second set of characters (9783_5453_9790) follows a pattern of increasing by 1, then decreasing by 1. Therefore, in the second set of characters, the fourth digit should be 4 instead of 3 to follow this pattern. This means that the answer is 27.

Question 11

If  is y a function of x?

Accepted Answer

The given string does not provide any information about the relationship between x and y, nor does it contain any mathematical operators or symbols commonly used to denote a function. Therefore, it cannot be determined if y is a function of x or not.

Question 12

If  , is y a function of x? ​

Accepted Answer

The given value is a series of alpha-numeric characters, which cannot determine if y is a function of x.

Question 14

Which of the graphs below represent y as a function of x? ​
(a)
​  (b)
​  ​

Accepted Answer

A function is a relation where each x value corresponds to only one y value. In graph (a) for each x value, there is only one y value. However, in graph (b) for some x values, there are multiple y values. Therefore, only graph (a) represents y as a function of x.

Question 20

Is the relation defined by the table a function of x? ​

Accepted Answer

In a function, each input (x-value) has only one output (y-value). In the given table, for each input (x-value), there is only one corresponding output (y-value). Hence, the relation defined by the table is a function of x.
