A function delivers an output based on an input. A given input will always result in the same output.

The function says: if the number is even, the output is x^2, but if the number is odd, the output is x+10

Results:
f(2): 4
f(7): 17
f(0): n/a

0 is even number=> f(0) = 0😉

1 A function is a computation/calculation applicable as a formula. The execution of the computation enable to apply these formulas and to optain outputs out of the inputs.
2.
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 (even)

A function is a series of input and output defined by a certain parameter provided.

a) 2 is even thus f(x)= 4
b) 7 is odd thus f(x) = 17
c) 0 is even thus f(x) =0

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

  1. Describe what a function does in your own words

A function receives a number or amount as an input, does a particular math action to it (it does a calculation which uses the input), and then gives / sends out a related output, which is the result of the math action (the solution to the math problem).

  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) = {x^2 if x is even, x+10 if x is odd} = 4

b) f(7) = {x^2 if x is even, x+10 if x is odd} = 17

c) f(0) = {x^2 if x is even, x+10 if x is odd} = 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
    A function takes one or more inputs, applies mathematical computations using those inputs to produce an output.

  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 (2^2)
  • b) f(7) = 17 (7+10)
  • c) f(0)
    This one is arguably debatable. I consider an odd/even number by using modulo.
    So:
    if (x % 2 > 0) even = false.
    else even = true.
    In this case, 0 is even as 0 mod (%) 2 == 0.
    So in that regard f(0) = 0
