What is the vertex of the graph of f(x) = |x – 13| 11?

(–11, 13)
(–13, 11)
(11, 13)
(13, 11)

Step-by-step explanation:

Assuming the function is

If an absolute value equation is given in this form:

The vertex will be:

Hence, from the equation given, we can easily see that the vertex is

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
