The graph of a function is given.
When the function of x is -3, that is
[tex]f(x)=-3[/tex]
That means the input value which is x, gives us negative 3.
Looking at negative 3 from the graph, the value of x where the graph equals negative 3 (on the vertical axis, or y-axis) is either negative 2 or 1. That is
Also, when the input of the function is zero, then you'll have the output as
[tex]f(0)=1[/tex]
This means when the value of x is zero, then the output as shown on the graph is 1 (that is the graph touches the y-axis at 1)
Therefore;
(a) One value of x for which f(x) = -3 is -2 (OR 1)
(b) f(0) = 1
