Answer:
Identity; conditional
Explanation:
Identity functions are functions that returns the SAME value which was used in its argument. In this case, f(x) = g(x). Therefore f(x) = g(x) = x.
Conditional functions are conditions that evaluates the condition and returns DIFFERENT values all depending on the condition value. That is, in this case, f(x) is not equal to g(x) for every x domain.
So, while identity functions returns the same value, conditional functions returns different functions.
Whoa just a second there.
What is the question ?
Is the question "Find the percent of increase ?"
In that case, the answer is 300% .
Here's why:
The amount of increase is 75.
The amount of increase as a fraction of
the original amount is
75 / 25 = 3.00 .
To change any number to a percent,
move the decimal point 2 places that way ===> .
3.00 = 300% .
______________________________
The question could have been different.
It could have been "What is the amount of the increase ?"
That's 75.
It could have been "How many times larger is 100 than 25 ?"
100 is 4 times as large as 25, and 3 times larger.
It could have been "How many times has 25 been increased ?"
This is a terrible question ... there are a lot of those in schools.
The answer could be "25 was only increased once, by 75."
The answer could be "25 was increased to 4 times its size."
The answer could be "25 was increased by 3 times its size."
