Question
Identify the correct graph for the equation.
y = 
–2
Hint:
Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.
The correct answer is:
Seeing the options, let’s check the point (5, 0).
If x = 5,
y = 
– 2 = 0
So, (5, 0) passes through the graph. That means it can be either graph A or graph C.
It is graph A as it is a reciprocal function and it has the shape of a hyperbola.
Hence, the correct option is A.
We can substitute the points lying on the graph to determine which is the graph of the given equation.
