Question

What is the domain of the function on the graph? A) all real numbers B) all real numbers greater than or equal to 0 C) all real numbers greater than or equal to –2 D) all real numbers greater than or equal to –3

Answer 1

Answer:

Clearly, the function has been plotted on the graph for values of x ranging from (-3,+infinity)

which means,

the domain of this function will be all real numbers greater than or equal to -3.

Answer 2

Given :  A graph

To Find :  domain of the function on the graph?

A) all real numbers

B) all real numbers greater than or equal to 0

C) all real numbers greater than or equal to –2

D) all real numbers greater than or equal to –3

Solution:

Domain :

The domain of a relation or a function is the set of all possible values for an input in that relation/function.

Range :

The range of a relation or function is the set of all possible values that can be the result of a relation or function.

From the graph there does not exist any thing on left side of x = - 3

and graph going towards infinity on positive x axis side

and  function is continuous

Hence Domain is all real number - 3 or greater than -3

Hence option D is correct

all real numbers greater than or equal to –3
