A figure is transformed. Which best describes the transformation of the figure? Original: A(7, 3), B(5, -3), C(3, 0) Image: A'(-7, 3), B'(-5, -3),C'(-3, 0)

x(t)=4cos(πt) -divide by 4

y(t)=3sin(πt) -divide by 3

x(t)/4 = cos(πt) -to the square

y(t)/3 = sin(πt) -to the square

x(t)²/16 = cos²(πt)

y(t)²/9 = sin²(πt)

Sum this:

x(t)²/16 + y(t)²/9 = cos²(πt)+sin²(πt)

x²/16 + y²/9 = 1.

a² is 16 and b² is 9 therefore a=4 and b=3.

Parametric equation of elipse is generally:

x(t) = a cos(f(t))

y(t) = b sin (f(t))
