How do you find interval of increase or decrease??

Mathematics

Virty [35]3 years ago

Using interval notation, it is described as increasing on the interval (1,3). Decreasing: A function is decreasing, if as x increases (reading from left to right), y decreases. In plain English, as you look at the graph, from left to right, the graph goes down-hill. The graph has a negative slope.

Giving 25 points for whoever answers it with a complete explanation .. ASAP
MAXImum [283]
No, it is not a function.
Since all the lines have been drawn in the grid line do not have any connection between them even a point in common.
I hope this has been useful for you.

Equation for 14+ W= 26
OLEGan [10]

Answer: w = 12

Step-by-step explanation: In this problem, we want to get <em>w</em> by itself on one side of the equation. Since we have <em>14 + W</em>, in order to get <em>w</em> by itself, we must subtract 14 from the left side of the equation.

If we subtract 14 from the left side of the equation, we must also subtract 14 from the right side of the equation. So on the left, +14 and -14 cancel each other and on the right, 26 - 14 simplifies to 12 so <em>w = 12</em>.

To check our answer, we substitute a 12 back in for <em>w </em>in the original equation and we have 14 + (12) = 26 or 26 = 26 which is a true statement so the answer checks.

B' (-3,-4) is the image of B after a reflection in the y-axis,What are the coordinates of B?
gladu [14]

Answer:

The coordinates of B will be (3,-4).

Step-by-step explanation:

If a point on the coordinate plane reflects across the y-axis then its y-coordinate will not alter but the x-coordinate will change by its sign only.

Now, if B'(-3,-4) is the image of B after a reflection in the y-axis then we can say B is the image point when the original point is B'(-3,-4) after reflection in the y-axis.

Therefore, the coordinates of B will be (3,-4). (Answer)
