Answer:
A .
Step-by-step explanation:
Here the degree of all equations (polynomial) are 2 but the leading coefficient of in all equation are different which are the following.
(1). The leading coefficient of in the equation is 4.
(2). The leading coefficient of in the equation is 3.
(3). The leading coefficient of in the equation is 2.
(4). The leading coefficient of in the equation is 0.5.
In the above four equations the leading coefficient of is greatest in the equation .
Hence the graph of is increases most rapidly.
