Question

2.

Which of the quadratic functions has the narrowest graph?


A.
`y=(1)/(8)x^2`

B.
`y=(1)/(3)x^2`

C. y = –2x2

D. y = –3x2

Answer 1

D. y = –3x2

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

• 
  `C)~y=-3x^2`
