Question

what is the axis of symmetry for y= x^2 + 4x + 3

Answer 1

Answer:

x = -2

Step-by-step explanation:

The coefficients of this quadratic are 1, 4 and 3.

                                                -b             -4

The axis of symmetry is x = --------- = ---------- = -2      =>       x = -2

                                                2(a)        2(1)
