The graph of g (x) = ax^2 opens downward and is narrower than the graph of f (x) = x^2. Which of the following could be the value of a?

-2.

Step-by-step explanation:

The value of a must be negative for the graph to open downwards also t be narrower than y = x^2 the absolute value of a must be greater than 1.

So - 2 could be a value of a.

Any number less than - 1

Step-by-step explanation:

Since you did not provide any of the answer choices, I will provide a rule.

Since it opens downward it must be negative, and since it is narrower, its absolute value must be greater than 1. So, it must be less than - 1
