The reference function is \(f(x)=x^2\)

The affine transformation is applied in this order: dilation of the y-coordinate by factor 1/2

Write the image rule in the form \(g(x)=Af(Bx+C)+D\)

Which rule represents the image curve, and what are its four coefficients?

(a)1 mark

Which rule represents the image curve, and what are its four coefficients?

\[g(x)=Af(Bx+C)+D\]
(b)4 marks

Enter the four coefficients in \(g(x)=Af(Bx+C)+D\)

Use the coefficients obtained directly from the coordinate map: A=sᵧ, B=1/sₓ, C=−tₓ/sₓ and D=tᵧ. Keep this representation rather than simplifying inside f
