Question

2.
Which of the quadratic functions has the narrowest graph?


A. $y=\frac{1}{8}x^2$

B. $y=\frac{1}{3}x^2$

C. y = –2x2

D. y = –3x2

Answer 1

Answer:

D. y = –3x2

Step-by-step explanation:

Answer:

y = -3x^2

Step-by-step explanation:

A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.

Answer 2

Answer:

• $C)~y=-3x^2$
