Question

Which function has a vertex at (2, 6)? f(x) = 2|x – 2| – 6 f(x) = 2|x – 2| + 6 f(x) = 2|x + 2| + 6 f(x) = 2|x + 2| – 6

Answer 1

b) f(x)=2Ix-2I+6

Explanation:

Answer 2

Using a vertex form for quadratic equation:
y=a(x-h)^2+k
where:
(h,k) is the vertex, an equation with a vertex (2,6) will be:
y=a(x-2)+6

thus our answer, given the choices will be:
f(x)=2Ix-2I+6
