Answer:

B. The graph of g(x) is horizontally stretched by a factor of 2.

Step-by-step explanation:

Since the 2 is 2x that means it is on the x line which is horizontal. So B is your answer.

Answer:

<h2>B. The graph of g(x) is horizontally stretched by a factor of 2.</h2>

Step-by-step explanation:

f(x - b) - the graph being shifted b units to the right.

f(x + b) - the graph being shifted b units to the left.

f(x) + c - the graph being shifted c units up.

f(x) - c - the graph being shifted c units down.

f(-x) - the graph being reflected across the y-axis.

-f(x) - the graph being reflected across the x-axis.

f(nx) - a horizontal compression by a factor of n.

f(x/n) - a horizontal stretch by a factor of n.

n f(x) - a vertical stretch by a factor of n.

1/n f(x) - a vertical compression by a factor of n.

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

We have f(x) = x² and g(x) = (2x)² → g(x) = f(2x/2).

Therefore the graph of g(x) is horizontally compressed by a factor of 2.

A pizza chain wants to send codes for $2 off a large pizza to the subscribers of its e-mail list. Each coupon code will have thr

kati45 [8]

Answer:

438,012 ways.

Step-by-step explanation:

We have been given that each coupon code will have three letters followed by two digits. The letters M, N, and O and the digits 1, 3, 5, and 7 will not be used. So, there are 23 letters and 6 digits that will be used.

Since the letters and digits can be repeated, so we will use fundamental principal of counting.

For first place, we can use 23 letters, for 2nd and 3rd place we can use 23 letters.

We can use 6 digits for 1st digit place and 6 digit for 2nd digit place as repetition is allowed.

So we can choose coupon code is following ways:

$23\cdot 23\cdot 23\cdot 6\cdot 6=438012$

Therefore, we can choose coupon codes in 438,012 ways.

Need help....... thx

Blababa [14]

I got 75582.

Explanation:

First, group the 40 identical candies into 20 pairs. It doesn't matter how since the candies are identical. This grouping will ensure that any assigment will contain at least two candies.

Then think of the 20 groups a 20 beads on a string. We are looking to place 11 separators between them to obtain 12 segments, each with a varying number of beads between them. How many ways are there to place 11 separators to 19 potential spaces between beads? The asnwer is $n = {19\choose{11}}=75582$

Expansions and compressions are transformations that change the length or width of the graph of a function.

To graph y = a*f (x)
if a> 1, the graph of y = f (x) is expanded vertically by a factor a.
We have then:
f (x) = 2/5 x ^ 2-2
The function g (x) is a vertical stretch of f (x) by a factor of 2:
g (x) = 2f (x)
g (x) = 2 (2/5 x ^ 2-2)
g (x) = 4/5 x ^ 2-4

Answer:
The equation of g (x) is:
g (x) = 4/5 x ^ 2-4
