Question

14. PLEASE HELP ME

Which of the quadratic functions has the narrowest graph?

A. y= 1/8x2

B. y= 1/6x2

C. y= -x2

D. y= 2x2

Answer 1

D. y= 2x2

Explanation:

y = ax^2

If the absolute value of a is <1 the graph is wider than when a = 1

If the absolute value of a is >1 the graph is narrow than when a = 1

The only function that fits that description is

y = 2x^2

B <<< answer.

Given: We are given equation of parabola ans to choose narrowest graph.

Parabola form narrowest and widest.

Larger value of a most narrowest graph.

Smaller value of a most widest graph.

Now, we will see the coefficient of x²

Now, we arrange the value of a in descending order.

2 is largest value of these.

Hence, The narrowest graph is
