The equation of the piecewise function is 
<h3>The piecewise function</h3>
On the graph, we have:
- y = 3 for all x values not more than -1
- y = -1 for all values greater than 2
Hence, the piecewise function is:
<h3>The domain of the function</h3>
This is the set of input values
In (a), we have:
x ≤ -1 and x > 2
Hence, the domain is (∞, 3] u (2, ∞)
<h3>The range of the function</h3>
This is the set of output values
In (a), we have:
f(x) = 3 and f(x) -1
Hence, the range is [3] u (-1)

The answer is 19
arrange the numbers from least to greatest
2,5,19,25,28
Then repeatedly cross one off from each end until there is only one left
5,19,25
19
The left side
1.99999925
1.99999925
does not equal to the right side
1
1
, which means that the given statement is false.
1. 1/9
2. 0
3. -9
4. -1
Reasoning: To get the opposite of a number just add a negative sign or take it away. This can be done to all numbers other than 0
Answer:
$5
Step-by-step explanation:
Her weekly allowance is $18
she downloads 3 songs , each song costs $2
18 - 2x3 = 18-6 = $12 left with her.
She uses $7 to go to the rock-climbing gym
$12-$7 = $5
She puts the rest ($5) in her college funds.
