Identify the vertex of each function

12. (4, 7)

13. (5, -1)

Step-by-step explanation:

Rewrite in vertex form and use this form to find the vertex (h, k).

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
