Answer:

As x → -∞, f(x) → 0.5; as x → ∞, f(x) → 0.5

Step-by-step explanation:

Given function:

f(x)=\dfrac{4x-7}{8x+8}

<u>Asymptote</u>: a line that the curve gets infinitely close to, but never touches.

As the degrees of the numerator and denominator of the given function are equal, there is a horizontal asymptote at  y=\dfrac{a}{b}  (where a is the leading coefficient of the numerator, and b is the leading coefficient of the denominator).  This is the end behavior.

\textsf{Horizontal asymptote}:y=\dfrac{4}{8}=\dfrac{1}{2}

This is because as x \rightarrow \infty the -7 of the numerator and the +8 of the denominator become negligible.  Therefore, we are left with:

f(x) \rightarrow \dfrac{4x}{8x}

Therefore:

\textsf{As }\:x \rightarrow - \infty, f(x) \rightarrow 0.5

\textsf{As }\:x \rightarrow \infty, f(x) \rightarrow 0.5

11. A square-shaped floor is covered with congruent square tiles. If the total number of tiles that lie on the two diagonals is
natita [175]

361 congruent square tiles would be needed to cover the square shaped floor.

<h3>Equation</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.

Counting one tile twice, there are:

  • 37=2x-1
  • x=19 tiles on each side.

19² = 361

361 congruent square tiles would be needed to cover the square shaped floor.
