Piecewise Function is like multiple functions with a speific/given domain in one set, or three in one for easier understanding, perhaps.
To evaluate the function, we have to check which value to evalue and which domain is fit or perfect for the three functions.
Since we want to evaluate x = -8 and x = 4. That means x^2 cannot be used because the given domain is less than -8 and 4. For the cube root of x, the domain is given from -8 to 1. That meand we can substitute x = -8 in the cube root function because the cube root contains -8 in domain but can't substitute x = 4 in since it doesn't contain 4 in domain.
Last is the constant function where x ≥ 1. We can substitute x = 4 because it is contained in domain.
Therefore:
The nth root of a can contain negative number only if n is an odd number.

Answer:
Algebra is the topic of the chapter
It is not a mixed number because if you put the same number of the numerator on the denominator it would be a mixed number (1)
20/100 = x/12
The 20/100 in the expression represents the 20%. The x in this scenario is the unknown amount in which the person will tip. The /12 is the cost of the original price. So, in order to find the value of x, you would need to cross multiply.
x = $2.40
The total cost would be $2.40 + $12.00 = $14.40
Answer:
a) 5s + 10a = 4500
s+a = 700
b) $2500
c) $1000
Step-by-step explanation:
a) Let students = s and adult = a
5s + 10a = 4500 -------1
s+a = 700 -------2
Using elimination metthod
Multiply eqn 2 by 5
5s + 10a = 4500
5s + 5a = 3500
Subtracting
5a = 1000
a =200
s = 700- 300= 500
b) if both tickets sell for $10 each
200*10 + 500*10 = $7000
Extra money that would have been made = 7000- 4500 =$2500
c) if s is $5 and a is $15
Tickets sold = 200*15 + 500*5 =$5500
Extra money made = $5500- $4500
= $1000
