Question

The graph of the following parabola will be narrower than the base graph of the parabola and be curved up f(x) = 2x^2 + 5x − 3.

Answer 1

Is this true because anything above 0 makes the parabola narrow and anything under 0 makes it wider?

Answer 2

yes

Answer 3

1/2 is wider

Answer 4

to make it wider it has to be between 1 and 0

Answer 5

-2 is still narrow

Answer 6

Do you mean

Is this true because |a| above \(\large \color{red}{1}\) makes the parabola narrow and anything under \(\large \color{red}{1}\) makes it wider?

Answer 7

@ganeshie8 yah thats the one i met :p I kinda screwed up there

Answer 8

the coefficient of x^2 is positive so it will be curved up
yes the 2 coefficient of x^2 will make the parabola narrower

Answer 9

ganeshie can you help with calculus?
