3 College Algebra Questions, See who can help me solving these...?

Question

1.) Is y=2x^2 - 5 symetric with respect to the x-axis, y-axis, or the origin?

2.) The Graph of y = (x-2)^2 would be shifted up, down, right, left; thinner or wider from/than the graph of y=x^2?

3.) The Graph of y = 3x^2 would be shifted up, down, right, left; thinner or wider from/than the graph of y=x^2?

I need to know how to do these, so can you please show me how you got the answer?

Thanks for your help.
