Consider the functions f(x) = -2(x-3)² + 2 which is represented by the graph
ehidna [41]

The intervals of the function on the graph are:

  • Domain = (-∝, ∝)
  • Range = (-∝, 2]
  • Increases (-∝, 3]
  • Decreases [3, ∝)

<h3>The key features of the function?</h3>

The function is given as:

f(x) = -2(x-3)² + 2

See attachment for the graph.

From the graph, we have;

Domain = (-∝, ∝)

Because it takes all real values as its input

Range = (-∝, 2]

Because it has a vertex of (3, 2) and the vertex is a maximum

Also, it increases on the interval (-∝, 3] and decreases on the interval [3, ∝)

At a park, there are 38 people playing tennis some or playing doubles and some are playing singles there are 13 matches in progr
dmitriy555 [2]
X = number of singles matches
y = number of doubles mnathes

so we have the equation x + y = 13.......(1)

also 

2x + 4y  = 38 ...........(2)

(1) and (2) are the required equations

b)  Find how many maches are in progress by solivng the above equations:-

x + y  =  13   multiply this by -2:-
-2x - 2y = -26
2x + 4y = 38   Adding to removes the  terms in x:-

2y = 12

y = 6  

so x = 13-6 = 7

So the answer is  6 double matches and 7 singles are in progress.

1. 7 + 5x = 3 - 2x and 7 + 7x = 3<br> Are they equivalent, if so what is X
oksano4ka [1.4K]

Answer: They are equivalent, and x = -4/7

Step-by-step explanation:

Fist we need to see what the answers to each of these equations are

7 + 5x = 3 - 2x

Subtract 7 on each side

5x = -4 - 2x

Add 2x

7x = -4

X = -4/7

Now the second one

7 + 7x = 3

Subtract 7

7x = -4

X = - 4/7

They are equal and x = -4/7
