PHOTO ABOVE PLEASE HELP

Can someone explain the answer for me? I am seeming to not get it.

Answer:

(-4,1)

Step-by-step explanation:

1. Reflection in the y-axis- if we are only focusing on A then you have to make the x negative:

A (-4,1) A' (4,1)

2. Reflection in the x-axis- make the y negative in the point A:

A' (4,1) A'' (4,-1)

3. Rotate 180 degrees- (x,y) rotated 180 degrees is (-x,-y):

A" (4, -1) A'''(-4, 1)

side note: if 1 is already negative than two negatives make a positive, which is why -1 becomes 1 after the 180 degree rotation

If X and Y are mutually exclusive events with P(X) = 0.295, P(Y) = 0.32, then P(X⏐Y) =

Kaylis [27]

Using conditional probability, it is found that P(X⏐Y) = 0.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which:

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that X and Y are mutually exclusive events, hence $P(X \cap Y) = 0$ , hence:

$P(X|Y) = \frac{P(X \cap Y)}{P(Y)} = \frac{0}{0.32} = 0$

Given the functions f (x)=\x] and g(x)= 2 x + 31 – 4 a. Determine the

Arisa [49]

Functions can be transformed through translation, dilation, etc.

The changes are horizontal translations and vertical compression.
The domain of f(x) is $(-\infty,\infty)$ , while its range is $(0,\infty)$
The domain of g(x) is $(-\infty,\infty)$ , while its range is $(-4,\infty)$

We have:

$f(x) = |x|$

$g(x) = 2|x - 3| - 4$

(a) The changes from f(x) to g(x)

First, f(x) was translated to the left by 3 units.

The rule is:

$(x,y) \to (x-3.y)$

So, we have:

$f'(x) = |x - 3|$

Next, the function is compressed vertically by 2

The rule is:

$(x,y) \to (x,2y)$

So, we have:

$f"(x) = 2|x - 3|$

Lastly, the function is translated down by 4 units.

The rule is:

$(x,y) \to (x, y - 4)$

So, we have:

$g(x) = 2|x - 3| - 4$

Hence, the changes are horizontal translations and vertical compression.

(b) Analyze f(x) and g(x)

f(x)

It spans across the x-axis; so, its domain is $(-\infty,\infty)$

The y values start from 0 and opens upward; so, its range is $(0,\infty)$

It crosses the x and y axes at 0; so its intercepts are 0.

g(x)

It spans across the x-axis; so, its domain is $(-\infty,\infty)$

The y values start from -4 and opens upward; so, its range is $(-4,\infty)$

It crosses the x-axis at -1 and -5; so its y-intercepts are -1 and -5

It crosses the y-axis at 2; so its x-intercept is 2
