Determine the domain and range of the function f(x) = â€""|x| 2. The domain of the function is. The range of the function is.

Answers

The domain of the function f(x)  =  |x|² is the set of all real numbers (-∞ < x < ∞)

The range of the function f(x)  =  |x|² is the set of all real numbers greater than or equal to zero ( f(x) ≥ 0)

The given function is:

f(x)  =  |x|²

This can also be expressed as:

f(x) = x²

This is because the square operator cancels the effect of the absolute value

The function f(x) = x² is valid for all real values of x. Therefore, the domain of the function f(x) is -∞ < x < ∞

The range of the function f(x) is all positive real numbers. This is because the square of all numbers gives a positive number.

Range = f(x) ≥ 0

What would be the equation of the midline of this graph?

Answers

Answer:

Step-by-step explanation:

Vertices of the quadrilateral ABCD are,

A → (-5, 2)

B → (-3, 4)

C → (-2, 4)

D → (-1, 2)

By reflecting the given quadrilateral ABCD across x-axis to form the image quadrilateral A'B'C'D',

Rule for the reflection of a point across x-axis is,

(x, y) → (x , -y)

Coordinates of the image point A' will be,

A(-5, 2) → A'(-5, -2)

From the picture attached, point E is obtained by translation of point A'.

Rule for the translation of a point by h units right and k units up,

A'(x+h, y+k) → E(x', y')

By this rule,

A'(-5 + h, -2 + k) → E(1, -1)

By comparing coordinates of A' and E,

-5 + h = 1

h = 6

-2 + k = -1

k = 1

That means

Rule for the translation will be,

[(x + 6), (y + 1)]

What is the graph of the function rule? y=|3x|+2

Options below!

Answers

Answer: the 4th/last option

Step-by-step explanation:

Y goes up when x goes down or up. When x = 0, y = 2

Step-by-step explanation: I like to have the 3 on the

outside and we can just write it as y = 3|x| + 2.

Now, we know that this is the form y = a|x - h| + k where

(h, k) represents the vertex of the function.

Notice that there is no value of h so we say that h = 0.

In addition, we know that k = 2 so our vertex is (0, 2).

This eliminates the first graph and the third graph.

Since a is positive, our function opens upward.

So graph 4 matches with our equation.

Solve for y. 4/7 y + 2/7 = 6

A) y = 20
B) y = -10
C) y = 10

Answers

Answer:

C) y = 10

Step-by-step explanation:

Subtract 2/7 from each side

4/7y = 40/7

Divide both sides by 4/7 (Multiply by 7/4)

y = 10

Answer:

C) y=10

Step-by-step explanation:

4/7y+2/7=6

7(4/7y+2/7)=7(6)

4y+2=42

4y=42-2

4y=40

y=40/4

which ratio is equivalent to the ratio 7:6

Answers

Answer:

B. 21:18

Step-by-step explanation:

7/6 x 3 = 21/18

This means they are equivalent.

Answer:

Option B is correct.

Step-by-step explanation:

Let's first turn 7:6 into a fraction:

=> 7:6 = 7/6

Now, let's simplify all the options to see which one is the correct answer.

Option A:

=> 14:18=> 14/18=> 7/9=> 7/9 ≠ 7/6

Therefore, Option A is incorrect.

Option B:

=> 21:18=> 21/18=> 7/6=> 7/6 = 7/6

Therefore, Option B is correct.

Option C:

=> 21:12=> 21/12=> 7/4=> 7/4 ≠ 7/6

Therefore, Option C is incorrect.

Option D:

=> 18:14=> 18/14=> 9/7=> 9/7 ≠ 7/6

Therefore, Option D is incorrect.

We can conclude that Option B is correct.
