Question

Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2(x + 7)2 - 4?

How would I find the Axis of symmetry?

Answer 1

x = -7

Answer 2

So, it's just the X intercept?

Answer 3

put y=0
get two x intercept
then find their mid pt
and find the corrosponding value of y

Answer 4

no, this is not the x intercpt.

Answer 5

or simply (x+7)^2=0
find x
then find y
there are two ways

Answer 6

to do it

Answer 7

axis of symetry is the turning point of the curve.

Answer 8

yes it is if it is a quadratic curve
the quadratic curve is symetrical about the turning pt

Answer 9

Alright. Thanks, guys!
