The notation f:S→T denotes that f is a function, also called a map , defined on all of a set S and whose outputs lie in a set T
AnnyKZ [126]

Answer:

There are many. Two examples are

f(x) = x, \\f(x) = x^3

Step-by-step explanation:

There are many examples. The simplest is

1 -

f(x) = x

It is trivial that

\text{if \,\,\,\,}  f(x) = f(y) \,\,\,\,\,\text{then} \,\,\,\,\, x=y

2 -

f(x) = x^3

That function is injective as well.

\text{if \,\,\,\,}  x^3 = y^3 \,\,\,\,\,\text{then} \,\,\,\,\, x=y

An example of a function that is NOT injective is

f(x) = x^2

Notice that

f(-2) = (-2)^2 = 2^2 = 4

Answer:

Part A: a histogram

Step-by-step explanation:

Part A:

A histogram would be the best to use since they gave values that are x - y, or a ranged amount for the score.

Part B:

You would set up each value for the scores on the bottom. You would make the number of students on the left in increments of 1 (1,2,3,4,5 etc. )

You would make the first value ( 0-4 ) go up to 4 students.  The second value ( 5-9) would go to 5. The third value ( 10-14 ) would go to 2. The fourth and fifth values ( 15-19 and 20-24 ) would go to 3.

Find X and Y. can someone please help me with this question, thank you
Arturiano [62]

3<em>x</em> + 120° + <em>x</em> + 120° = 360°

4<em>x</em> + 240° = 360°

4<em>x</em> = 120°

<em>x</em> = 30°

<em>y</em> = 1/2 (3<em>x</em> - <em>x</em>)

<em>y</em> = 1/2 (90° - 30°)

<em>y</em> = 1/2 × 60°

<em>y</em> = 30°
