Please help me find DOMAIN/RANGE and the EQATION

Mathematics
1 answer:
kaheart [24]3 years ago
4 0

Answer:

domain:

( -  \infty , \infty )

range:

( -  \infty ,4]

equation:

y =  - 2(x - 3) {}^{2}  + 4

Step-by-step explanation:

domain is all X values and the X values will extent till infinity in both negative and positive direction, the range is all y values and the y value will go from negative infinity all the way to 4, where the graph stops.

The graph below shows the solution to which system of inequalities?
Rus_ich [418]

Inequalities help us to compare two unequal expressions. The inequalities that represent this graph are y<8/10x and y>-x. The correct option is C.

The complete question is:

The graph below shows the solution to which system of inequalities?

A.) y>x , y ≥ (8/10)x

B.) y>-x, y ≤ (8/10)x

C.) y>-x, y < (8/10)x

D.) y>x, y > (8/10)x

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

To find the inequality, we need to find the equation of the dashed line and then substitute the inequality as per the requirement. The dashed line is used instead of a solid line to show greater than or less than.

The inequality for the first graph can be written as,

y < \dfrac{8}{10}x

The inequality for the second graph will be,

y>-x

Hence, the inequalities that represent this graph are y<8/10x and y>-x. Thus, the correct option is C.

4 (2x + 3) = 4x + 24 + 6x – 6
omeli [17]

Answer:

-3 = x

Step-by-step explanation:

4 (2x + 3) = 4x + 24 + 6x – 6

8x + 12 = 10x + 18

12 = 2x + 18

-6 = 2x

-3 = x

Write an inequality for the graph.
kap26 [50]

Answer:

y ≤ |x – 5| + 5

Step-by-step explanation:

The graph below has the vertex (5,5). This means that in the equation the function has been shifted up by addition of 5 and shifted right by subtraction of 5. This means y ≤ |x – 5| + 5 or y ≥ |x – 5| + 5 are the only options.

To determine, test a point from the shaded region like (0,0).

y ≤ |x – 5| + 5 is the solution.
