  1. Describe what a function does in your own words

A function is a mathematical computation consisting of an input and an output.

  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)

b) f(7)

c) f(0)

Output a = 4
Output b = 17
Output c = 0

3. 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

The parity of zero is even. 0^2=0 (defined)

#749

7 is odd, so 7 + 10 = 17

#750

The parity of zero is even. So 0^2=0

#751

When x is even, you need to do x^2
When x is odd, you need to do x+10

4
17
0

#752

Ok thanks. That was sort of a guess anyway.

Thanks… I think I must have calculated 7 x 10 instead of 7 + 10.

whoops :slight_smile:

  1. a function takes a particular input and produces a certain output based on the equation of the function

a) f(2) = x2^2
=> output = 2
b) f(7) = 7+10
=> output = 17
c) f(0) = 0^2
=> output = 0

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

Describe what a function does in your own words

A function is a series of events that produces a reliable outcome.

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) = error

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
