Darnell is counting the number of vehicles that pass through an intersection per hour. Based on his count, he writes a function that approximates his data. What number set serves as the domain of Darnell's function? a

all whole numbers greater than or equal to 0
b

all real numbers
c

all whole numbers
d

all real numbers greater than or equal to 0

irrational, cannot

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: its the third option.
