Question

consider the graph of the following qyadratic equation. y=x^+4x-5 what is the axis of the symmerty?

Answer 1

Answer:

The axis of symmetry is at x=-2

Step-by-step explanation:

The axis of symmetry, h , is found at

h = -b/2a  where a and b are the coefficients of the equation in standard form

                         y = ax^2 +bx +c

        y = x^2 +4x+5

   a =1    b=4   c=5

Then

h =- 4/2(1)

   = -2

The axis of symmetry is at x=-2
