  1. Describe what a function does in your own words
  • Computation of given an “Input” value as a parameter which is then calculated to provide an “output” is known as function.
  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) = 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.
f(x) = {
    division = x/4
    result = division - 5
}

  1. A function takes an input, does computation on the input, and returns an output.

  2. a) f(2) = 4
    b) f(7) = 17
    c) f(0) = Undefined

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

  1. A function takes an input and gives an output. (The function describes what to do with the input to get an output)

  • a) f(2) = 4
  • b) f(7) = 17
  • c) f(0) = 0

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

a) 2 is even, f(2) = x^2 = 2^2 = 4
b) 7 is odd, f(7) = x+10 = 7+10 = 17
c) 0 is even , f(0) = 0 = x^2 = 0^2 = 0

1.) Functions are computations with inputs and outputs that define a uniqe relationship between independent and dependent variables. Using “X” and “Y”, if, when a numerical value is assigned to X (input), a unique value of Y is determined (output), Y would then be a function of the independent variable, X.

2.) f(x)=

 f (2^2) = 4
 f (7+10) = 17
 f (0^2) = 0

3.) f (x/4) - 5 =
f (80/4) - 5 =
f (20 - 5) = 15

Thank you for the correction, Maki, I miss interpreted the question in the sense that it was asking for two outputs. I really Appreciate it; if you ever want to have a chat and bounce ideas off of one another with this course, send me a message sometime and we can work from there. :grin:

  1. Describe what a function does in your own words

It applies certain mathematical rules to our input so we get a result

  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)

a) f(x)= 4

• b) f(7)
f(x)=17

• c) f(0)
f(x)=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
A function is a mathematical operation that takes an input and performs a calculation to result in an output.

2.
a = 4
b = 17
c = no output or an error (I don’t think 0 is considered an even number. So there are not matching conditions)

3.
f(x) = ( x / 4) - 5
