  1. a function is a computation with an input and an output that is designed around the mathematical equation.

  2. f(2) = 2^2 since it is an even number.(4)
    f(7) = 7+10 since it is an odd number. (17)
    f(0) = 0^2 since it is an even number. (0)

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

Homework on Functions - Questions

  1. Describe what a function does in your own words
    A function is a program and its purpose is to calculate an output based on the input. It uses a variable called x, this variable can represent the input number to achieve a mathematical equation. (eg x = 2)

  2. 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.
    The function would look like the following: Input = x, (x / 4) - 5 = output

Yeah, I assumed something like that :wink:

  1. A functions takes some kind of input, does calculations on that input, and returns that as function output.

  2. The output of said function will be:
    a) (f2) = 4, as 2 is an even number and the function will thus raise input to the power of two
    b) f(7) = 17, as 7 is an odd number, and the function will thus add 10 to the input
    c) f(0) = 1, as 0 is an even number - anything raised to the power of zero must equal 1 (although some argue that 0 raised to the power of zero can not be defined!)

f(x) = {

x = x / 4

x = x - 5

}

  1. A function is a mathematical device that applies a specific step or steps to a value. You apply the specified step or steps of a function to an input value. Applying the steps of the function render an input as a value or calculated result of the specific steps or parameters that are applied to the input.

  2. 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)
  • b) f(7)
  • c) f(0)

Answer:
A.4
