In maths, f (x) means as a special relationship where every single input has one output.
<u>Step-by-step explanation:</u>
In mathematics, a function is any expression that gives exactly one answer for each particular number. Input is the number provided in the expression, and output is the number obtained from the search or calculation.
In an ordered pair, input’s first number corresponds to the horizontal axis, and output’s second number in the vertical axis. These ordered pairs can then be plotted. Some data on the costs associated with this are called relationships. For example,

It is often written as "f (x)" where x is the input value and
is the output value.
Answer:
rational
Step-by-step explanation:
the equation above would be -10 making it an integer
integers are rational
Step-by-step explanation:
Doubled of 132 which means 2 times 132 =
Subtract 12 doubled from 132
While write the expression whatever the expression after the word from that we have to write first
So Doubled of 132 - 12
- 12 -----> This is the final expression
If we simplify the above expression we will get
264 - 12
= 252
