Answer:

The graphs shown is NOT a function.

Step-by-step explanation:

We can use Vertical Line test to determine whether a given relation in the graph is a function or not. A relation is a function if one input results in only one output. If we draw vertical lines on the graph, and any of these vertical line intersect the graph at 2 or more positions, then it means that for one value of x, there are 2 values of y. Hence, for one input, there are more than one outputs. Therefore, the relation will not be a function.

We can see in the attached graph below that any vertical line intersects the graph at 2 positions. Hence, the given relation is graph is not a function.

Apologies for the rough drawing.

You can apply the same technique for the graph of the relation which is not shown, you'll get your answers to fill in the blanks

The image of C reflected across the line x = 3 would have the coordinates ________________.

kipiarov [429]

Using translation concepts, the image of C reflected across the line x = 3 would have the coordinates (4,-2).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a reflection across the line x = 3 is given by:

(x,y) -> (3 + |x - 3| , y).

The coordinates of C are C(2,-2), hence:

(2,-2) -> (3 + |2 - 3| , -2) = (4,-2).

The image of C reflected across the line x = 3 would have the coordinates (4,-2).

Right answer gets BRAINYESST

Mariulka [41]

Answer:

check all below

Step-by-step explanation:

1/6)^3

1/26 so answer 1 on number one

#2 what the heck is this 65+75= 140 not 120

65/120 = 54.16666% * 12600 = 6825 so 3

or 65/140 = 46.428% * 12600 = 5850

#3 number 4 makes the most since sense you get the WHOLE POPULATION

#4 1/5*1/2 or 1/10 = .10 * 100% = 10% or 3

6+2+8+4 = 20

2 red marbles

2/20 = 1/10 = .10 * 100% = 10% or 2

Rewrite the function by completing the square. f(x) = x2 – 10x + 44 + f(x) = (x+

iVinArrow [24]

Answer:

$f(x)=(x-5)^{2}+19$

Step-by-step explanation:

we have

$f(x)=x^{2}-10x+44$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-44=x^{2}-10x$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$f(x)-44+25=x^{2}-10x+25$

$f(x)-19=x^{2}-10x+25$

Rewrite as perfect squares

$f(x)-19=(x-5)^{2}$

$f(x)=(x-5)^{2}+19$

Rhombus ABCD has a diagonal BD¯¯¯¯¯. m∠ADB=(5x+10)° m∠CDB=(4x+19)° What is the m∠ADC ? Enter your answer in the box º

Lorico [155]

Answer:

110°

Step-by-step explanation:

5x+10=4x+19

5x-4x =19-10

x = 9

m L ADB = 5(9)+10=45+10=55°

so m L ADC = 2×55° = 110°
