If you want to shift the graph of a function <em>horizontally left</em>, then you <em>add</em> some amount to the x-value. If a <em>horizontal right</em> shift is needed, then you <em>subtract</em> from the x-value.

Furthermore, if you wish to move your graph <em>vertically up</em>, then <em>add</em> to the y-value (the function itself). And <em>subtract</em> from it for a <em>vertically down</em> shift.

Now, we need a <em>horizontal </em><u><em>3</em></u><em> unit left</em> shift. That means we <em>add </em><u><em>3</em></u> to the x-value, without touching the function itself. The function is \mathrm{F}(x)=x^2, hence the shifted function is \mathrm{G}(x)=(x+3)^2.

What is the range of the function?
AleksAgata [21]
The range of the function on the graph is all real numbers greater than or equal to 2 because the range of a function is what the value of y could be, and y begins at 2 and keeps increasing indefinitely.
Hope this helps!

Inessa [10]

Answer:

For this distribution of test scores, the standard deviation is equal to the square root of 9

D) 9

Step-by-step explanation:

We need to know the standard deviation formula:

S=\sqrt{\frac{sum(x-Am)^2}{n-1} } (1)

Where:

S: Standard deviation

sum: Summation

x: Sample values

Am: Arithmetic mean

n:   Number of terms, in this case 3

Now, we need to know the arithmetic mean of the sample values: 2, 5 and 8

Am=\frac{2+5+8}{3} = 5

To know the standard deviation we need to have the summation of each term minus the arithmetic mean squared.

(x-Am)^2 of each term:

(2-5)^2=9\\(5-5)^2=0\\(8-5)^2=9

Now, we can find the standard deviation:

S=\sqrt{\frac{9+0+9}{3-1} } \\S=\sqrt{\frac{18}{2} } \\S=\sqrt{9}

The standard deviation is equal to the square root of 9
