HI everyone for the last calculation what is the correct way to write it. ??
should it be two seperate functions ???
Have i done it correctly ???

A function is a process that calculates basic computations

a] 4
b) 17
c) 0

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

It flips and folds it the same way
Whatever value you put in.
A=4
B=17
C=0
f(x)=(x/4)-5

1 - A function is a computation that takes something (ie. a number) as input and it will give something back as an output (ie. a number).

2 - a. output = 4
b output = 17
c output = 0

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

  1. Describe what a function does in your own words.
    It is a system of computation that takes an input, can perform a mathematical operation on it, and then return an output

  2. f(2) = 4
    f(7) = 17
    f(0) = 0

  3. f(x) = { ((x/4) - 5 ) }

  1. Describe what a function does in your own words
  • A function take a parameters and that parameters is used to do some math process
  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) => even ( ^ ) => output => 2 * 2 = 4
  • b) f(7) => odd ( + ) => output => 7 + 10 = 17
  • c) f(0) => not defined => output not defined => same number => 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.
// multiple lines
f(x) {
 return (x/4) - 5;
}

// one line
f(x) => (x/4) - 5;

  1. A function is and input that gives you some type of output.

  2. a) f(x)=x^2, f(2)=4 The answer is 4

  3. b) f(x)=c+10, f(7)=10 the answer is 10
    2 c) f(x)=x^2, f(0)=0 The answer is 0

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