How do you do this problem? I think I have the domain and range part: D: (-3,5] R: (-2,-5)

Given:
A graph of a function y = f(x).
Required:
Determine the properties asked in question.
Explanation:
a).
[tex]Domain\text{ of a function=\lbrack-3,5\rparen}[/tex]b).
[tex]Range\text{ of a function=\lbrack0,-5\rbrack}[/tex]c).The x intercept is (-3, 0).
d). The y intercept is (0, -2).
e). Function is Decreasing at
[tex][-3,-2)\cup(0,3)[/tex]and increasing at
[tex](-2,0)\cup(3,5)[/tex]The value of function at f(-2) = -3 and f(3) = -5.
Answer:
Hence, above is the answers.
