Reflection Functions
Mathematics In a Nutshell
The function is reflected by the position of - and knowing the rules described in and will be very helpful to your math skills.
Reflection in the x-axis
y = - f(x)
Grey : y = x^2
Purple : y = -x^2 (reflection in the x-axis applied)
Example 1
y = -√x
Example 2
y = -3^x
Reflection in the y-axis
y = f(-x)
Grey : y = log(x)
Purple : y = log(-x) (reflection in the x-axis applied)
Example 1
y = 2^-x
Example 2
y = √-x
