4. PLEASE HELP ME Which of the quadratic functions has the widest graph?

A. y= -4/5x2

B. y= -4x2

C. y= 1/3x2

D. y= 0.3x2

D. y= 0.3x2

Step-by-step explanation:

In quadratic functions, the value of a affects the wideness of the graph. The smaller the absolute value of a, the wider the graph. In these choices, 1/3 and 0.3 are the smallest. To understand which is smaller convert both to decimals; 1/3 is 0.3333 repeating. Therefore, 0.3 is slightly smaller and wider.

the answer is 0.071

good luck! : d
