Question

2. What is the vertex of the function (x) = 1x – 34– 17 (A) (B) (C) (3,1) (39–1) (-3,-1) (-3,1)

Answer 1

if we have a function in the standard form as follows.

$f(x)=|x\pm h|\pm k$

Then the vertex is (h, k) or the point where the function changes the sign.

Therefore the vertex is (3, -1) or the option (B).
