The graph of f(x)=x2 is horizontally stretched by a factor of 2 and then shifted to the left 2 units and down 4 units. Which equation describes the function g that results?

Answers

Answer 1
The equation of that function is:
y = (1/2 (x + 2) ) ^2 - 4
Answer 2

Using shifting concepts, it is found that function g is given by:

[tex]g(x) = \frac{x^2 - 4x - 12}{4}[/tex]

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

Horizontally stretching a function f(x) a units is the same as finding [tex]f(\frac{x}{a})[/tex]Shifting a function f(x) a units to the left is the same as finding f(x - a).Shifting a function f(x) down a units is the same as finding f(x) - a.

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

The parent function is:

[tex]f(x) = x^2[/tex]

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

Horizontally stretching by a factor of 2.

[tex]f(\frac{x}{2}) = (\frac{x}{2})^2 = \frac{x^2}{4}[/tex]

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

Shifting left 2 units:

[tex]f(\frac{(x-2)}{2}) = \frac{(x - 2)^2}{4} = \frac{x^2 - 4x + 4}{4}[/tex]

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

Shifting down 4 units:

[tex]g(x) = f(\frac{(x-2)}{2}) - 4 = \frac{x^2 - 4x + 4}{4} - 4 = \frac{x^2 - 4x + 4}{4} - \frac{16}{4} = \frac{x^2 - 4x - 12}{4}[/tex]

When a standard pair of six sided dice are rolled, what is the probability of getting a 6?
(Express your answer as a decimal rounded to the thousandsth place.)

Answers

Answer:

0.5 because it has a total of 6 sides

Probability of getting a 6 is equal to
1 - the probability of not getting a six.
The probability of not getting a six on a single roll is 5/6. The probability of not getting a 6 for 2 rolls is (5/6)^2.
The probability of getting a six is

1 - (5/6)^2 = 11/36.

Hye Lim drank 4/3 gallons of water in 11/2 hours. At this rate, how long will it take her to drink 4 gallons of water?

Answers

Answer:

16.5 hours

Step-by-step explanation:

Here is the explanation. As Hye drinks 4/3 gallons of water in 11/2 hours, we have a constant rate. There are 12 thirds in 4, so we are trying to find how long it takes Hye to drink 12/3 gallon. In this case, 4/3x3=12/3, so we multiply 11/2 by 3 as well, which gives us 33/2 hours. 33/2 in decimal form is 16.5 hours. Hope it helps!

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

y = cos(2x)

The x-intercept of the equation in the interval 0 ≤ x < 2π will be given as,

y = 0

cos(2x) = 0

cos 2x = cos (n + 1) π/2

2x = (n + 1)π / 2

x = (n + 1)π / 4

x = π/4, 3π/2, 5π/4, 7π/4

The solution of the equation y = cos(2x) will be π/4, 3π/2, 5π/4, and 7π/4. Then the correct option is D.

Radical and rational expression equations can have extraneous solutions. For radical equations, they are typically ones that require a negative square root (or negative root of even index). For rational expression equations, they typically involve "excluded" values, values that make a denominator be zero.

Step-by-step explanation:

Notice that the first the transformation is a rotation of 90 degrees around the origin, and then a reflection around the x axis.

If a reflection around the x axis resulted in (3, 0)  that means the point was already on the x axis.

Then in order for a rotation in 90 degrees to take the point Y to (3, 0), Y must have been on the y-axis as (0, 3)
