Question

Example of Domain Input and Range Output

Answer 1

The Solution:

Suppose we have a function given as below:

$y=f(x)=2x+1$

Whatever values x takes are examples of domain input while the corresponding values of y for each value of x are examples of range output. For example, let the values of x be -1, 0, 1, 2,... So, the corresponding values of y will be

$\begin{gathered} \text{ when x=-1,} \\ y=2(-1)+1=-2+1=-1 \end{gathered}$

When x =0,

$y=2(0)+1=0+1=1$

When x = 1

$y=2(1)+1=2+1=3$

When x = 2

$y=2(2)+1=4+1=5$

So,

Domain input = {-1, 0, 1, 2,...}

Range output = {-1, 1, 3, 5,...}
