# The ordered pair given in the first row in the table can be written using function notation as?A. (f)1=-2B. (f)-2=-2C.(f)-2=-1f(x) = β2 when x is? A. -4B. 1C. 4

Accepted Solution

A:

These are two questions and two answers.

Question 1. The ordered pair given in the first row in the table can be written using function notation as?

Answer: f(-2) = 1

Justification:

In functions, the notation f(x) denotes the image (ouput) obtained when you apply the rule (function) to the value x, i.e. x is the input.

So, for example, the image of x = 5 is f(5), the image of x = 2,000 is f(2,000), the imaga of x = - 100.5 is f(-100.5).

In the table, the first row shows that the image of x = -2 is 1, so f(-2) Β = 1, and that is the answer to the question.

Question 2. f(x) = β2 when x is?

Answer: x = 4.

Justification.

You are requested to find which value of x makes the function f(x) equals Β -2.

Therefore, you have to see that in the third row of the table it is shown that f(x) is - 2 when x = 4., and that is the answer.

All the following expressions mean the same and are used when you deal with functions: the ordered pair (4, -2), the image of 4 is - 2the preimage of -2 is 4f(4) = -2f(x) = -2, when x = 4.
