Question

What is the turning point of this function?

f(4)= |4+2|=6
the lines are for absolute value.

Answer 1

absolute value functions are v-shaped. I hthink the turning point you're referring to is the vertex. This is where the inside of the absolute value is zero.

f(x) = |x+2|
0 = x+2
-2 = x

vertex (-2,0)
