Question
For the function 
- -2
- -1
- 0
- 1
Hint:
This question is about a function. A function is a relation between two sets such that every element of first set is related to only one element in second set. In this question, we are given the relation between the input and output of the function. We are asked to find the value of function for a specific value.
The correct answer is: 0
iThe given function is 
We have to find the value of f(-2)
When we substitute the value of x in the function, we get the value of the function for that input.
Here, we have x = -2
We will replace all the x in the above equation by -2. Then, we will solve the equation and get the required value.
So, for the given function f(-2) = 0.
For such questions, we should know the concept of the function.

City tours rents bicycles for $10 an hour with a maximum daily fee of $100. Show the cost for renting bicycle for 1, 3, 11, and 20 hours.
The cost of renting a bicycle is $ 100 per day. The maximum fair is $ 100 for any number of hours a day. If we have to find a random number of hrs, we can Multiply the number of hrs by the amount of the rent for that particular hour. That gives the total rent for that particular hour.
Eg: cost of renting bicycle for 1 hour = $10 x 1 = $10
