Transformation Rules

Which is a rule for a reflection over the x-axis?

• $f\left(x,y\right)=\left(x,-y\right)$

• $f\left(x,y\right)=\left(-x,y\right)$

• $f\left(x,\ y\right)=\ \left(-y,\ x\right)$

• $f\left(x,\ y\right)=\ \left(y,-\ x\right)$

Which rule shows a dilation with a scale factor of 2?

• $f\left(x,y\right)=\left(x+2,\ y+2\right)$

• $f\left(x,y\right)=\left(\frac{1}{2}x,\frac{1}{2}y\right)$
