## Homework Statement

First example f(x)=1/4 (x+4)^2 +7

Asks for vertex and the line of symmetry and the value of f(x) and maximim or minimum

This is no problem vertex= (-4,7) line of symmetry is -4 value f(x)= 7

second problem f(x)=x^2 -10x -2

vertex (5, -27)

but now ask for the equation of the line of symmetry

Is:

__the line of symmetry__and:

__the equation of the line of symmetry__the same thing?

information shows the line of symmetry is x= - b/2a. okay so how do I show this as an equation if the line of symmetry is 5
