I understood this when we went over it in class, but I can't remember how to figure this out.
y-axis: (x,y) then (-x,y)
x-axis: (x,y) then (x,-y)
origin: (x,y) then (-x,-y)
Is the following symmetric to the x-axis, y-axis or origin?
y=4x^3-6x
To figure this out I follow the above rules.
Origin: -y=-4x^3- (-6x) Multiply by -1
(-1)-y=(-1)-4x^3-(-6x)
y=4x^3-6x
{Answer: Yes}
y-axis: y=-4x^3 - (-6x) {Answer: No}
x-axis: -y=4x^3-6x {Answer: No}
Did I do this correctly?
