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

first looks correct, second one is not...

Answer 2

what do u think the second one is

Answer 3

well, if you're looking for how wide a function is, it typically has to do with the leading coefficient's absolute value (we don't need to worry about the negatives since all that does is flip the graph along the x-axis). wider functions have smaller ones, while narrower functions have larger ones

i would have said answer one

Answer 4

thanks alot :)

Answer 5

No problem! I'm glad to help! :D
