Question

Identify the axis of symmetry for the graph of f(x) = (x - 3)2 + 1. Enter your answer as the following example: x = 1

Answer 1

Axis of symmetry: x = -b/2a

Answer 2

Distribute, add like terms, and plug the terms into the equation

Answer 3

how do u add like terms?

Answer 4

x+2x = 3x ...

Answer 5

Add the coefficients.

Answer 6

what?

Answer 7

i got f(x)=2x-5

Answer 8

What's that?

Answer 9

idk lol

Answer 10

Will be back later. But f(x) = 2x-5 is not the answer to this symmetry question.
I made a mistake in my previous post, the correct version is like this:

If the quadratic equation is in the form of y = a(x-h)^2 +k, the axis of symmetry is x=h, the min/max value is k and the vertex is at (h,k).
Note that the question given in your question is in this form, so compare it with your equation, find the value of h.
