  1. Describe what a function does in your own words
    Function is form of a math computation where there is an input and it solves to give 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)
b) f(7)
c) f(0)

  • a) f(2) = 2^2 = 4
  • b) f(7) = 7+10 = 17
  • c) f(0) = 0 (if there is no input there is no output)
  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 with its own words

Function is a relation attributed to a variable that determines the other variable.

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 exit for the following entries?

a) f (2) = 2 ^ 2 = 2 * 2 = 4

b) f (7) = 7 + 10 = 17

c) f (0) = 0 ^ 2 = 0

3 - Write the definition of a function f that receives an input x, divides it by four and produces that result subtracted by 5.

f (x) = y = x / 4 - 5, then:

f (2) = y = 2/4 - 5 = - 4.5

    Just wondering if anyone be kind enough to check my answer? I’m struggling to include the ‘=’ sign…Looks like you all have an ‘=’ but doesn’t f(x) / 4-5 produce the same definition? Or must function have an ‘=’ equal sign to make it a function? Thank you for your time.

A function is allows a formula that calculates a variable. In this case the variable is x. Additionally, we have conditions checking the x variable for even or odd.

A.
f(x) = x^2
f(2) = 2^2 = 4

B.
f(x) = x+10
f(7) = 7+10 = 17

C.
f(x) = x^2
f(0) =0^2 = 0

f(x) = (x/4) - 5
Following the order of operations, that function will first divide by 4 before subtracting 5.
