Question

What are the coordinates of the vertex of the graph of f(x)=−3|x−1| ?

Enter your answer as an ordered pair without parentheses in the box.

Answer 1

−3|x−1|
= −3(x−1)
= -3x +3

-3x +3 = 0
-3x = -3
x = 1

−3|x−1|
= −3[-(x−1))
= -3(-x -1)
=3x + 3

3x + 3 = 0
3x = -3
x= -1

order pairs: -1 and 1
