Answer:

The range of the function is all real numbers less than or equal to 9.

Step-by-step explanation:

Given : The function f(x) = –x2 – 4x + 5 is shown on the graph.

To find :  Which statement about the function is true.

Solution : We have given that f(x) = –x² – 4x + 5 .

Domain :  domain are the set of input values on which the function is defined or real.

F(x) is not undefined for any value.

Then , (-∞ , ∞)

Range : range is the set of values dependents variable on which function is defined.(-∞ ,0]

Therefore, The range of the function is all real numbers less than or equal to 9.
