ex) f(x)=m(x)=2
Vector: something that has only two characteristics
Magnitude: size or quantity of a vector]]> 2017-03-15 16:19:25 UTC https://padlet.com/reeseop/fh3al05csdeh/wish/160302703 reeseop https://padlet.com/reeseop/fh3al05csdeh/wish/160304319 Affect the y-value:
f(x)=g(x)+k      shifts up
f(x)=g(x)-k      shifts down
Affect the x-value:
f(x)=g(x+k)      shifts left
f(x)=g(x-k)      shifts right
Reflection across x-axis:
f(x)=-g(x)
Reflection across y-axis:
f(x)=g(-x)
Stretch vertically:
f(x)=kg(x)
Stretch horizontally:
f(x)=g(kx)
