Answer:
f(-3) = -2
f( 1 ) = - 1
If f(x) = -2, then x = 3
If f(x) = 2, then x = -5
Step-by-step explanation:
Looking at the graph, we can easily determine the value of the given functions.
f(-3) = -2 (This function basically asks, if x = -3, what is the value of y? In the graph, it shows that the value of y is -2).
f( 1 ) = - 1 (Similarly, this function asks, if x = 1, what is the value of y? In the graph, it shows that the value of y is -1).
If f(x) = -2, then x = ? ←← For this particular question, you're given the value of y = -2. All you need to do is look at the graph to see what is the value of x given that y = -2. Even though it is not clearly labeled on the graph, it shows the value of x = 3 (it is right where the end arrow is located).
Therefore, If f(x) = -2, then x = 3.
If f(x) = 2, then x = ? ←← Similar to the previous question, you're given the value of y = 2. In the graph, one of the given points has the coordinates of (-5, 2). This gives you the value of x = -5.
Therefore, If f(x) = 2, then x = -5.
