If a quadratic function is given as G(x) = x^2 - 3, what transformation has occurred?

• Shifted left 3 units

• Shifted down 3 units

• Shifted up 3 units

• Shifted right 3 units

In the function G(x) = (x + 2)^2, what does the '+2' inside the parentheses indicate?

• Shifted 2 units down

• Shifted 2 units to the right

How do you identify if a function is vertically stretched or shrunk?

• By checking if the function has parentheses

• By looking at the coefficient of x

• By looking at the constant term

• By checking if the coefficient of x^2 is greater than or less than 1

What does a negative sign outside the parentheses in a quadratic function indicate?

• Reflection over the y-axis

• Reflection over the x-axis

• Horizontal shrink

• Vertical stretch
