QuestionFor each relation, decide whether or not it is a function.
Relation 1
Range Function Not a function

Studdy Solution

STEP 1

What is this asking? Is this thing a function or not, basically, can one input have multiple outputs? Watch out! Don't mix up domain and range!
The question is, does any element in the domain point to more than one element in the range?

STEP 2

1. Check the mappings.

STEP 3

$h$ goes to $\bf{2}$ .
Okay, so far so good!
One input, one output.

STEP 4

$k$ goes to $\bf{2}$ .
Still good!
It's fine if different inputs go to the same output.

STEP 5

$w$ goes to $\bf{0}$ .
Looking great!

STEP 6

$a$ goes to $\bf{0}$ .
Perfect! Each input has exactly one output.

STEP 7

It's a function!
Every element in the domain maps to exactly one element in the range.

Studdy Solution

STEP 1

What is this asking? Is this thing a function or not, basically, can one input have multiple outputs? Watch out! Don't mix up domain and range!The question is, does any element in the domain point to *more than one* element in the range?

STEP 2

1. Check the mappings.

STEP 3

hhh goes to 2\bf{2}2.Okay, so far so good!One input, one output.

STEP 4

kkk goes to 2\bf{2}2.Still good!It's fine if *different* inputs go to the *same* output.

STEP 5

www goes to 0\bf{0}0.Looking great!

STEP 6

aaa goes to 0\bf{0}0.Perfect! Each input has *exactly one* output.

STEP 7

It's a **function**!Every element in the domain maps to exactly one element in the range.
