Answer:

<u>Parent function</u>

f(x)=\log_2(x)

Since we cannot take logs of zero or negative numbers, the domain is (0, \infty) and there is a vertical asymptote at x=0.

There are no horizontal asymptotes and the range is (- \infty,\infty).

The end behaviors of the parent function are:

\textsf{As } x \rightarrow 0^+, f(x) \rightarrow - \infty

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

To determine the attributes of the given function, compare the given function with the parent function.

<u>Given function</u>

<u />f(x)=- \log_2(x)+5

The given function is <u>reflected in the x-axis</u>.  Therefore, the end behaviors are a reflection of those of the parent function:

\textsf{As } x \rightarrow 0^+, f(x) \rightarrow \infty

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

As the given function is <u>translated vertically</u> (5 units up) only, the domain, range and asymptote will not change, since the function has not been translated horizontally.

\textsf{Domain}: \quad (0, \infty)

\textsf{Range}: \quad (- \infty, \infty)

\textsf{Asymptote}: \quad x=0

<u>Conclusion</u>

The function f(x) is a \boxed{\sf logarithmic}} function with a \boxed{\sf vertical}} asymptote of \boxed{x = 0}.  

The range of the function is \boxed{(- \infty, \infty)}, and it is \boxed{\sf decreasing} on its domain of \boxed{(0, \infty)}.  

The end behavior on the LEFT side is as \boxed{x \rightarrow 0^+}, \boxed{f(x) \rightarrow \infty}, and the end behavior of the RIGHT side is \boxed{x \rightarrow \infty}, \boxed{f(x) \rightarrow -\infty}.

Find the solutions of the quadratic equation by finding the square root: x2 - 3 = 7.
Masja [62]

Answer:

<em>x = - √10, and x =√10</em>

Step-by-step explanation:

1. Let us add 3 to either side of the equation: x^2 - 3 + 3 = 7 + 3

2. That equation would simplify to: x^2 = 10

3. Now let us take the square root on either side: √x^2 = √10

4. Being square root of x^2, we could say that: | x | = √10

5. And thus 2 answer may be derived from this equation provided absolute value symbol ( | | ): <em>x = - √10, and x =√10</em>

At Elisa's Printing Company LLC there are two kinds of printing press: Model A which can print 70 books per day and Model B whic
NeX [460]

Answer:

Number of Model A press = 9 and Number of Model B press = 5

Step-by-step explanation:

Number of books Model A can print per day = 70

Number of books Model B can print per day = 55

Let x be the number of Model A press and y be that of Model B press.

Total number of printing presses = 14

x + y = 14  ----------------1

Total number of books printed per day = 905

70x + 55y = 905-------2

Putting y = 14 - x in equation 2, we get:

70x + 55(14 - x) = 905

15x = 135

x = 9

y = 14 - 9 = 5

Hence number of Model A press is 9 and that of Model B press is 5.

3 + 1.2 x &gt; 13.50 <br> can someone please help me
saveliy_v [14]

Answer:

The answer is x > 8.75.

Step-by-step explanation:

1) Subtract 3 from both sides.

1.2x > 13.50 - 3

2) Simplify 13.50 - 3 to 10.5.

1.2x > 10.5

3) Divide both sides by 1.2.

x >  \frac{10.5}{1.2}

4) Simplify 10.5/1.2 to 8.75.

x > 8.75

<u>Thus</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>x</u><u> </u><u>></u><u> </u><u>8.75</u>.
