Question

What is the equation of the axis of symmetry for the parabola y equals start fraction two over three end fraction left parenthesis x minus two right parenthesis squared minus five? x equals start fraction two over three end fraction x = −2 x = 2 x = −5

Answer 1

so hmm check the picture below

keep in mind, the equation is already in vertex form, and thus, the vertex is clearly at 2 , -5

anyhow, notice the axis of symmetry, the red line
