Answer:
Step-by-step explanation:
let th numbers be x and y.
x+y=21
y=21-x
Product P=xy=x(21-x)=21 x-x^2
P'=21-2x
P'=0 gives 21-2x=0,x=21/2
P"=-2
which is less than 0 at x=21/2
so P is greatest at x=21/2
y=21-21/2=21/2
P=21/2 ×21/2=441/4=110.25
The x-intercept is the x-coordinate of a point where a graph intersects the x-axis and the y-intercept is the y-coordinate of a point where a graph intersects the y-axis. For example, (-4,0) -4 is the x-intercept and (0,6) 6 is the y-intercept

Expand,

=

So the third choice would be your answer!

Answer:
The total Cost of 2 candies is $6.00.
Step-by-step explanation:
We are told that f(x) represents the cost of candy, and that x represents the number of candies.
f(2) means that x=2, which is 2 candies; f(2) = 6 means that the cost of 2 candies is $6.
