Find the domain and range of the relation and determine whet

Find the domain and range of the relation and determine whether it is a function.

A. domain: all real numbers; range: all real numbers; Yes, it is a function.

B. domain: positive integers; range: positive integers; No, it is not a function.

C. domain: x 0; range: y > 3; No, it is not a function.

D. domain: x > 3; range: y > 0; Yes, it is a function.

Solution

Solution:

Here the graph given is similar to the function e^x.

Hence there\'s no doubt about it being a fuction.

Domain: reach of x-axis

i.e

here;

x>3 is the values it can take.

Range:

y-axis reach.

here;

y>= 0 the range of the graph shown

with an asymptote at x = 3.
