The graph's values for the function are as follows:
f(-2) = 2
f(0) = 3
f(4) = -1
The graph displays a discontinuous inequality equation.
Points of discontinuity are breaks in the graph caused by an undefined point when the f(x) function is substituted with a non-solution x point.
We can plainly observe from the graph of the provided function f(x) that the function f(x) increases in the interval (-,0) and then drops in the interval (0,).
In addition, the function finishes at x=0.
(Because the graph has a gap and the function's left and right-hand bounds are not equal at x=0)
So we can deduce the values of the functions from the graph as,
f(-2) =2
f(0) = 3
f(4) = -1
