Which function represents the widest parabola? explain your reasoning. A . y = 2( x + 3 )^2
B . y = x^2 − 5
C . y = 0.5(x − 1 )^2 + 1
D . y = − x^2 + 6

C

Step-by-step explanation:

The coefficient on the x^2 tells you how wide of narrow the parabola is.

Coefficients greater than 1 get more narrow.

Coefficients less than 1 (and greater than 0) get wider.

If the coefficient is negative, ignore the negative in terms of finding the width of the parabola.  The negative just means it's pointing down, but that doesn't impact the width.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
