Which of the following relations is a function?

1 answer:

7 0

A function will NOT have any repeating x values, it can have repeating y values, just not the x ones. So which set has NO repeating x values ?
That would be { (1,3), (2,3), (4,3), (9,3)}....like I said, there can be repeating y values....just not the x ones. All of ur other answer choices have repeating x values.

If the point (3,-4) is dilated by a scale factor of 74 , what are the new coordinates?

Delvig [45]

Answer:

(-222, 296)

Step-by-step explanation:

Given point

(3, -4)

Dilation by a scale factor of 74:

(x, y) → (74x, 74y)
(3, -4) → (74*3, 74(-4)) = (222, -296)

Rotation by 180°:

(x, y) → (-x, -y)
(222, -296) → (-222, 296)

What’s the slope and y intercept of all of them

Anestetic [448]

Answer:

See below:

Step-by-step explanation:

Take the difference between y values of any two values and divide by difference in corresponding x values

for example, 1: 66-50/4-1=16

2. 36-30/8-6= 6/2=3

3. 63-56/8-7= 7/1 = 7

4. 100-78/9-7= 22/2 = 11

you can choose any two points, not just the two I used.

What happens to the sign or signs of the coordinates when you reflect a point?

elena55 [62]

Part a: Reflecting a point across the x-axis, changes the sign of the y-coordinate.

Part b: Reflecting a point across the y-axis, changes the sign of the x-coordinate.

Part c: Reflecting a point across both the axes, changes the signs of both the coordinates.

Explanation:

Part a: Reflecting a point across the x-axis

The reflection is a transformation of a figure which represents a flip.

The rule for a reflection over the x -axis is given by

$(x, y) \rightarrow(x,-y)$

Hence, this represents the change of sign of the y-coordinate.

Thus, Reflecting a point across the x-axis, changes the sign of the y-coordinate.

Part b: Reflecting a point across the y-axis

The rule for a reflection over the y -axis is given by

$(x, y) \rightarrow(-x, y)$

Hence, this represents the change of sign of the x-coordinate.

Thus, Reflecting a point across the y-axis, changes the sign of the x-coordinate.

Part c: Reflecting a point across both the axes

The rule for a reflection across both the axes is given by

$(x, y) \rightarrow(-x, -y)$

Hence, this represents the changes the signs of both the coordinates.

Thus, Reflecting a point across both the axes, changes the signs of both the coordinates.
