x(a)/x(b)=x(a-b)
[x(a)](b)=x(axb)
x(0)=1
x(-a) = 1/x(a)
x(1/n) = nth root of x
x(m/n) = [nth root of x](m) - 2Equation of image and image of y=f(x) for: translation of Ai+Bjx by (x-a)
y by (y-b)
y-b=f(x-a)
y=f(x-a) + b - 3Equation of image and image of y=f(x) for: reflection in x-axisy by -y
-y=f(x)
y=-f(x) - 4reflection in y-axisreplace x by -x
y=f(-x) - 5Equation of image and image of y=f(x) for: Strech factor k in x-directionreplace x by 1/kx
y=f(1/kx) - 6Equation of image and image of y=f(x) for: Stretch scale factor k in y-directiony by 1/ky
1/ky = f(x)
y = kf(x) - 7how to find limit of converging sequence? A=? d=?replace un and un+1 by l, form equation and solve
