Question

Can you tell me if these look correct(i picked the ones with the stars beside them)

Which of the following has a graph that is wider than the graph of y = 3x² + 2?

y = 3x² + 3

y = 0.5x² + 1****

y = –4x² – 1

y = 4x² + 1

What is the order, from narrowest to widest graph, of the quadratic functions f(x) = –10x², f(x) = 2x², f(x) = 0.5x²

f(x) = –10x², f(x) = 2x², f(x) = 0.5x²

f(x) = 2x², f(x) = –10x², f(x) = 0.5x²

f(x) = 0.5x², f(x) = 2x², f(x) = –10x²

f(x) = 0.5x², f(x) = –10x², f(x) = 2x²****

Answer 1

f(x) = –10x², f(x) = 2x², f(x) = 0.5x² would be my choice.
