Answer:
See Explanation
Step-by-step explanation:
A positive integer is a perfect square if it can be expressed as the product of two same positive integers.
Any number that cannot be written this way is a non-perfect square.
Since the integers are not presented, we will quickly examine the perfect squares between 1 and 50.
The perfect squares are: 1,4,9,16,25,36 and 49.
- 1=1 X 1
- 4=2 X 2
- 9=3 X 3
- 16 =4 X 4
- 25 =5 X 5
- 36 =6 X 6
- 49 =7 X 7
Every other positive integer in the numbers 1-50 apart from those listed above is a non-perfect square.
Answer:
Domain: [0, 40]
Range: [0, 20]
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Range is the set of y-values that are outputted by function f(x)
- Interval Notation - [a, b] denotes inclusive, (a, b) denotes exclusive
Step-by-step explanation:
According to the graph, we see that our x-values span from 0 to 40. Since both are closed dots, they are included in the domain:
Interval Notation [0, 40]
Inequality Notation 0 ≤ x ≤ 40
According to the graph, we see that our y-values span from 0 to 20. Since both are closed dots, they are included in the range:
Interval Notation [0, 20]
Inequality Notation 0 ≤ y ≤ 20
Answer:
67
Step-by-step explanation:
With the information of f(2) = 22-5, you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67
-1.5 ------ f(x) = 3(-1.5) - 5
= -4.5 -5
= 9.5
2 -------- f(x) = 3(2) - 5
= 6 -5
= 1
4 -------- f(x) = 3(4) - 5
= 12 - 5
= 7
(9.5, 1 , 7)
