Question

What is the range of the graph below?

[-4, infinity)
(-4, infinity)
(-infinity, -4)
(-infinity, -4}

Answer 1

Given:

The graph of a function.

To find:

The range of the graph.

Solution:

Domain: The set of input values are called domain.

Range: The set of output values are called range.

From the given graph it is clear that the function is defined for all real values of x but the output values are lie between $-4\leq y<\infty$.

So, the range of the graph is

$Range=\{y|-4\leq y<\infty\}$

The interval notation of the range is:

$Range=[-4,\infty)$

Therefore, the correct option is A.
