  1. A function takes a number or expression as an input, does a computation on it, and then provides an output which is equal to the result of the computation.
  • a) f(2) = 4
  • b) f(7) = 17
  • c) f(0) = undefined

f(x)=x/4-2

  1. Describe what a function does in your own words
    A function allows the user to input data, which then computes an about output based on the function parameters.

  2. Calculate the output of the following function
    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.

  1. Describe what a function does in your own words.
    Function is a computational BLOCK that takes in some kind of input and produces an output based on the calculations that are programmed into the function.

  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.

  1. A function is a hard-coded set of calculations or formulas using input variables to return the computed value or values as output.
  • a) f(2) = 4
  • b) f(7) = 17

  1. Describe what a function does in your own words

A function is the receiver of the input. A function is a computation. It does the calculation.
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) = 2 is even so it means f(2)=2^2 (looking at the answers ^ is the sign for multiplication) so the answer is 4
  • b) f(7) = 7 is odd so it means f(7)=7+10= 17
  • c) f(0) = neither odd nor even?
  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)/4=x(-5)=

Iā€™m really bad with math, hope I can grasp a bit of this
