Question

what is the vertex of the function y=3(x-7)+4

Answer 1

As the equation is presented in Vertex Form, this is an eyeball problem. Just look at it and write down the answer about as quickly as you can read it.

Vertex: (7,4) Done.

I assumed you meant y = 3(x-7)^2 + 4

Answer 2

No, that's what I thought as well but the equation is written correctly

Answer 3

Well, then it makes no sense.

(x-7)^2

or

|x-7|

THEN the re is a vertex.

There is NO vertex with just (x-7)
