Question

The graph of y = x 2 is changed to y = x 2 - 3. How does this change in the equation affect the graph? The parabola shifts 3 units up. The parabola shifts 3 units down. The parabola becomes 3 units wider. The parabola becomes 3 units narrower.

Answer 1

Please, use " ^ " to indicate exponentiation: y+x^2, y=x^2 - 3.

Subtracting 3 from y = x^2 causes the entire graph of x^2 to be translated downward 3 units.

Answer 2

Answer: The parabola shifts 3 units down.

Step-by-step explanation:

when you add (-3) to y = x^2 it becomes y = x^2 - 3

the (-3) tells you to shift the parabola three units down.
