The function f(x) = –x2 – 4x + 5 is shown on the graph. which statement about the function is true? the domain of the function is all real numbers less than or equal to −2. the domain of the function is all real numbers less than or equal to 9. the range of the function is all real numbers less than or equal to −2. the range of the function is all real numbers less than or equal to 9.

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.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
