## Question:

Which function is represented by the graph ?

We are given graph of an absolute function:

The standard form of an absolute function is :

y=a|â€‰xâˆ’hâ€‰|+k, where (h,k) is the vertex of the graph.

For the given graph of absolute function, we have vertex at (0,1).

And because it’s open down the value of a should be a negative number.

|a| >1, it would vertically stretch by a factor of 2.

### f(x)=-2|x| + 1.

They can easily hopefully help the student answer the question by make use of the questions and answer examples. You could potentially then have a discussion with your classmate and continue the school learning by studying the problem together with each other.
