1.start a solving math problem which we put.

  1. f(2^2) = 4

f(7^2) = 14

f(0^2) = 0

f(2+10) = 12

f(7+10) = 17

f(0+10) = 10

3.f(x/4) = 5 – x is 20

  1. Describe what a function does in your own words
    Function perform a random input in order to create a specific output.It generates specific results according to information that puts in.

  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

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

First you have to see if x equals even or odd.
this operater: ^ Means a power relation. 7^2 = 7x7 (not 14)

  • a) f(2) (2 is even) = 2^2 output = 4
  • b) f(7) (7 is odd) = 7+10 output = 17
  • c) f(0) (0 is even) = 0^2 output = 0

  1. A function, generally notated as an “f” in calculus, is a mathematical function that corelates the input with the output, depending on how the function is set up. This is best illustrated by the answers to question #2 above:
  1. f(x) = x^2 = 2^2 = 4
  • f(x) = f(x+10) = 7+10 = 17
  • f(0) = 0^2 = 0
  1. f(x) = f(x/4) minus 5

  1. A function describes the process which ought to be applied to a given input in order to generate an output. It can be applied to any given generic input, also negative, and follows mathematical rules.
  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)

2a: f(2)=2^2=4
2b:f(7)=7+10=17
2c:f(0)=0^0=0

  1. 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

2 is even, so 2^2 (2 to the power 2) = 4
ps. you shouldn’t use f() in the answers, It suggests to do another function
