  1. A function is a mathematical equation, using a letter as a variable(input) and the rest of the equation is consistent. The final answer or output of the equation will vary depending on what number is inputted for the letter, usually X.

2.A) if x=2 then f(x) =4
B) if x=7 then f(x)= 17
C) if x=0 then f(x)= 0

  1. F(x)= X/4 -5

  1. Describe what a function does in your own words
    A function is a mathematical form of input and result. You begin with a question and end with a solution.

  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.
    f(x) = (x ÷ 4) - 5

A function processes entered data and outputs the result of the processing.

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

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

  1. it repeats the math as programmed = input (plus rule) --> output
  2. 3, 14, 0

These two are not correct, you must either square the number if its even or add 10 if its odd. What was your process that gave you these results?

1- A function is a computation, which has an input and according to the defined computation gives us an output.

2-
f(2)= 22 (since it’s even) = 4
f(7)= 7+10 (since it’s odd) = 17
f(0)=02 = 0

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

    1. Describe what a function does in your own words…

A function makes a calculation based on parameters such as input and syntax. The result of this calculation is called the output.

    1. Calculate the output of the following function

f(x) = {

x^2 if x is even

f(2x2) = {4}

x+10 if x is odd

f(7+10) = {17}

}

What will be the output for the following inputs?

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