Question

Find the vertex of each function.
f(x) = 2 (x+3)^2 - 5
f(x) = 1/4 |x-5|+2

Answer 1

(-3, -5), (5, 2)

Explanation:

The answer was found by seeing the "vertex" part. For example, the vertex part of a parabola function is (x+whatever)^2, and the one for the absolute value is |whatever|. Plus shifts left and minus shifts right, plus shifts up and minus shifts down on the outside.
