Find the hole in the graph of the function f(x)=(x−2)(x+3)(x−2)(x+4)
Thus, x=2 is a hole in the graph.
Step 1 :First, we simplify the function. We notice that x−2 appears in both the numerator and the denominator, we can cancel this out.
Step 2 :After simplification, our function becomes f(x)=x+3x+4. However, the original function was undefined at x=2.
Step 3 :Thus, x=2 is a hole in the graph.
