According to the graph, what are the domain and range of f(x)


Plz Help According To The Graph What Are The Domain And Range Of Fx class=

Sagot :

Space

Answer:

Domain: [0, 40]

Range: [0, 20]

General Formulas and Concepts:

Algebra I

  • 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
