The graph of y=f(x) contains the point (2,-8). What point must lie on the reflected graph if the graph is reflected about the x-axis and y-axis?

Solution

Reflected about x-axis :
The pt (x,y) changes to (x,-y)

So, 2,-8) becomes (2,8)

----------------------------------------------------

Reflection in y-axis :
The pt (x,y) becomes (-x,y)

So, (2,-8) becomes

(-2,-8)
