y = -0.60x - 4
because the slope stays the same because it is parallel and the y intercept for the new equation ends up being -4
The vertex form of the function gives the vertex as (-6,48). The vertex of f(x)=x^2 is (0,0) so from this information, the vertex is moved LEFT 6 and UP 48. This cancels out two options. The coefficient -3 tells us that the graph is flipped or reflected over the x-axis (negative sign flips graph) and that all y-values will be 3 times as large. Larger y-values for the same x inputs makes the graph narrower.
If the circumference is half of the perimeter than the area for both circles would be half of them find one circles area and half it
