If you reflect (–2, –8) across both axes, which quadrant will it be in? Justify your reasoning.

stepan [7]

The quadrant would be the first one, because once reflected over the y-axis, it would become (2,-8), and once reflected over the x-axis, it would become (2,8)

State the vertex and axis of symmetry of the graph of y=ax2+c.

Neporo4naja [7]

State the vertex and axis of symmetry of the graph of y=ax^2+c

General form of quadratic equation is $y=ax^2 + bx +c$

There is no bx in our given equation, so we put 0x

Given equation can be written as $y=ax^2 + 0x +c$

a=a , b=0

Now we use formula to find vertex

$x=\frac{-b}{2a}$

$x=\frac{-0}{2a}=0$

Now we plug in 0 for 'a' and find out y

$y=a(0)^2 + 0x +c= c$

So our vertex is (0,c)

The axis of symmetry at x coordinate of vertex

So x=0 is our axis of symmetry
