Answer 1

Hi Carrie,

 

 

Algebra II
Find the axis of symmetry of the given function f(x) = x² - 7x + 6
Question 5 options:

 

The axis of symmetry for a quadratic equation is a vertical line and uses the x-coordinate of the vertex.

 

The x-coordinate of the vertex can be found using the formula 

x=-b

    ---

     2a

 

for f(x) = x² - 7x + 6

 

a=1

b=-7

c=6

 

x=-(-7)

    -----

      2(1)

 

x=7/2

 

ANSWER:  The axis of symmetry is x=7/2 or as a decimal x=3.5

 

Carrie, I hope this helps you understand the process.
