Could someone please check this answer.
Given y= x^2, how would the graph of y= x^2-2 differ?
A. It shifts 2 units up
B. It shifts 2 units down
C. It shifts 2 units left
D. It shifts 2 units right
Answer: B
If you graph each one on the same grid, you will see that the first one was moved downwards 2 units.
So is my answer right or no??
I thought I said that.
yes, it is B
Ok thanks for all your help. Sorry about the confusion.
To check the answer, we need to understand the effect of the change in the equation on the graph.
The original equation is y = x^2, which represents a parabola that opens upwards and is centered at the origin (0, 0).
Now let's examine the change in the equation: y = x^2 - 2. By subtracting 2 from the equation, we are shifting the entire graph downward by 2 units.
Therefore, the correct answer is B. It shifts 2 units down.
