  1. Describe what a function does in your own words

*a mathematical protocol

  1. Calculate the output of the following function
f(x) = {

x^2 if x is even

x+10 if x is odd

}

What will be the output for the following inputs?

  • a) f(2) = even x2 = 4
  • b) f(7)= odd +10 =17
  • c) f(0)= no value = 0
  1. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.

f(x)= (x/4)-5

  1. Describe what a function does in your own words
    Ans : In function we can provide mathematical operation to perform in desired way

  2. Calculate the output of the following function
    Ans :

  • a) f(2) - 4
  • b) f(7) - 17
  • c) f(0) - 0
  1. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.
    Ans : f(x) = (x / 4) - 5

1- function will execute some kind of mathematical equation to the input to produce an output.
2- f(2) = 4
f(7) = 17
f(0) = 0

3- f(x) = {
x/4-5
}

1 a function just describes an input and its output, a calculation

2
a x = 4
b x = 17
c x = 0 is not defined in the function above

  1. A function takes the input values and performs a defined mathematical task on them to produce an output value. It performs an action with these parameters (calculation / string manipulation / validation checks /…) and returns a result.

a) 4
b) 17
c) 0

  1. f(x) = {(x/4) - 5}

1.) A function predefines how to arrive at an output from a variable input.
2.a) 4
2.b) 17
2.c) 0^2, which would basically be “error” :slight_smile:
But most say 0^2 is zero. Possible. I’m not a mathematician.
3.)
f(x) = {
(x/4)-5
}
