Try this ACT math practice question on horizontal and vertical shifts of parabola and the resulting change in their equation:
In the $(x, y)$ coordinate plane, the graph of the parabola $y=-x^2$ is shifted 3 units up and 2 units to the left. Which of the following is an equation of the translated parabola?
- $\quad y=-(x-2)^2-3$
- $\quad y= -(x-2)^2 + 3$
- $\quad y=-(x+2)^2+3$
- $\quad y=-(x+2)^2-3$
- $\quad y=-(x+3)^2+2$
