____ [38]

Answer:

\large\boxed{\dfrac{x+1}{x}=1+\dfrac{1}{x}}

Using the functions s = 13.5h, which statement is true?
Archy [21]

A function is a relationship between inputs where each input is related to exactly one output.

The domain of s = 13.5h are (0, 1, 2, 3, 4).

The range of s = 13.5h are (0, 13.5, 27, 40.5, 54).

<h3>What is a function?</h3>

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

s = 13.5h

For h = 0,

s = 0

For h = 1,

s = 13.5

For h = 2,

s = 27

For h = 3,

s = 40.5

For h = 4,

s = 54

We see that,

The domain of s = 13.5h are (0, 1, 2, 3, 4).

The range of s = 13.5h are (0, 13.5, 27, 40.5, 54).

Thus,

The domain of s = 13.5h are (0, 1, 2, 3, 4).

The range of s = 13.5h are (0, 13.5, 27, 40.5,  54).
