A hotel offers a reward program based on the number of night stayed. The function f(x) represents the number of free nights earn

iris [78.8K]

Answer:

a. A customer earns 1 free night per 10 nights stayed.

Step-by-step explanation:

The missing function is:

f(x) = x/10

The missing options are:

<em> a. A customer earns 1 free night per 10 nights stayed. </em>

<em> b. A customer starts with 1 free night and then earns another free night after every 10 nights stayed. </em>

<em> c.A customer earns x – 10 free nights for every 10 nights stayed. </em>

<em> d. A customer earns 10 free nights after x number of nights stayed. </em>

The function means that after a customer stayed 10 nights, a free night is earned. That is, replacing x = 10 into the function, we get:

f(10) = 10/10 = 1

which means 10 nights are equivalent to 1 free night.

18 divide by 2 * 3/5-2 simplify show all work

liraira [26]

Answer:

Step-by-step explanation:

I would guess it looks like this - if not then tell me

$\frac{18}{ \frac{2 \times 3}{5 - 2} }$

2×3=6

5-2=3

Then there's only

$\frac{18}{ \frac{6}{3} }$

Which is equal to

$\frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9$

What are the domain and range of this function?

RUDIKE [14]

<h3>Answer: Choice D</h3>

Domain: all real numbers
Range: $y \ge 1$

===========================================

Explanation:

The domain is the set of allowed x inputs. We can plug in any x value we want as the graph stretches on forever to the left and to the right. There aren't any division by zero errors or any issues like that to worry about, so that's why we don't kick out any x values from the domain.

The domain being all real numbers translates to the interval notation $(-\infty, \infty)$ which is basically saying $-\infty < x < \infty$

-----------------------------------

The range is the set of y outputs possible. The graph shows that y = 1 is the smallest y output, so y = 1 or y can be greater than this.

In short, $y \ge 1$ is the range which converts to the interval notation $[1, \infty)$ which is the same as saying $1 \le y < \infty$

-----------------------------------

Extra info:

The equation of this absolute value function is y = |x|+1
