What is the vertex of the absolute value function defined by f(x)=|x-2|-7?
2 answers:
Answer: (2,-7)
Step-by-step explanation:
We know that ,
The general form of absolute value function :
, where (h,k) is representing the vertex.
The given absolute value function:
which can be written as
When we compare the given absolute function to its general form , then we get
h=2 , k= -7
⇒ The vertex of the function is : (2,-7)
Hence, the correct answer is (2,-7) .
