Can someone please help me i cant understand it?

A system of equations contains at least two equations and can have zero, one, multiple or infinite many solutions.
From the activity review, we have the following breakdown:
Assume the system of equations are:
f(x) = 2x + 4
g(x) = x² - 4
Solving by table
Start by creating a table of values for the above equations
x -3 -2 -1 0 1 2 3 4
f(x) -2 0 2 4 6 8 10 12
g(x) 5 0 -3 -4 -3 0 5 12
From the above table of values, we have:
f(x) = g(x) when x = -2 and when x = 4
Hence, the solutions to the system of equations are (-2,0) and (4,12)
Solving by graph
Start by creating a graph of the equations using a graphing tool.
From the attached graph, we have the point of intersection to be
(-2,0) and (4,12)
Hence, the solutions to the system of equations are (-2,0) and (4,12)
