Question

Use the graph of y = f(x) to find each value.

4. f(-4)=
5. f(1) =
6)
For what value of x is f(x) = -4?
--10--

Answer 1

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.
