The function f(x) = 4x – 0.1x2 is used to model the curve of a bridge over a small river, where x is the distance from one side of the river and the x-axis represents the ground. The mathematical range for the function is the set of real numbers.
Answer
A
The limitation for the reasonable range restricts it to positive real numbers.
B
The limitation for the reasonable range restricts it to positive whole numbers.
C
The limitation for the reasonable range restricts it to real numbers greater than or equal to 0 and less than or equal to 40.
D
The limitation for the reasonable range restricts it to whole numbers greater than or equal to 0 and less than or equal to 40.
