Which table of values could be used to graph g(x), a reflection of f(x) across the x-axis?

Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping $f(x)\mapsto -f(x)$

So, if you have a x/y values table, you simply have to change sign to all the values in the y column.

A point with a positive x-coordinate and a negative y-coordinate is reflected over the y-axis.

Luden [163]

The x-coordinate is negative, and the y-coordinate is negative.

This is because the y-axis is vertical, so reflecting across it means you will change the sign of the x-value, and the sign of the y-value will stay constant. Since we start off with a positive x and negative y, we will end up with a negative x and negative y.

Ratling [72]

Answer:a

a

$m = 57.5$

b

$\= x = 50.14$

Step-by-step explanation:

From the question we told that

The stem plots for American League is

$2\\3\ \ \ \ \ 5\\4 \ \ \ \ \ 0\ 3 \ 9\\5 \ \ \ \ \ 1\ 4\ 7\ 8\ 8\\6 \ \ \ \ \ 4\ 8\ 8\\7 \ \ \ \ \ 5\ 7$

Here the first column is the tens while each digit in the in the second column is the unit of the first column

For example row 3 means

40 , 43, 49

The sample size is n = 14

Generally the median is mathematically represented as

$m = \frac{ K + Z}{2}$

Here K is the $(\frac{n}{2}) th \ term \ in \ the \ data \ given$ i.e $\frac{14}{2} = 7th \ term$

From the stem plot the 7th term is 57

And

K is the $(\frac{n}{2} + 1) th \ term \ in \ the \ data \ given$ i.e $\frac{14}{2} + 1 = 8th \ term$

From the stem plot the 8th term is 58

Thus the median is

$m = \frac{ 57 + 58}{2}$

=> $m = 57.5$

The stem plots for National League is

$2\ \ \ 9\\3\ \ \ \ 1\\4 \ \ \ \ 2\ 6\ 7\ 8\ 8\\5 \ \ \ \ 3\ 5\ 5\ 5\\6 \ \ \ \ 3\ 3\ 7\\7\\$

Generally the mean is mathematically evaluated as

$\= x = \frac{\sum x_i}{n}$

$\= x = \frac{29 + 31 + 42 + 46 + 47 + 48 + 48 + 53 + 55+ 55+ 55+ 63+ 63+ 67}{14}$

$\= x = 50.14$

The price of a technology stock has dropped to $9.60 today. Yesterday's price was $9.67. Find the percentage decrease. Round you

beks73 [17]

Answer:

0.7% off

Step-by-step explanation:

$\frac{9.6}{9.67} =\frac{y}{100}$

9.67 × y = 9.6 × 100

9.67y = 960

9.67y ÷ 9.67 = 960 ÷ 9.67

$y=9\frac{267}{967}$

y = 99.2

100% - 99.2% = 0.8%
