Answer:
4. f(-4)= -1.
5. f(1)= -2.
6. For what value of x is f(x) = -4? x=4.
Explanation:
When asking, for example, for f(-4), it just means that you have to give the value of the graph when the x value is -4.
4. f(-4).
In this question you need to ask "What value of y shows the graphic when x is -4?"
f(-4)= -1.

5. f(1).
In this question you need to ask "What value of y shows the graphic when x is 1?"
f(1)= -2.
Check attached image 2.
6. For what value of x is f(x) = -4?
Now we need to ask the opposite of what we asked before, "What value of x shows the graphic when y is -4?"
x= 4.
