The function to describe the order of the mail-order company is given by f(x) = 5 +2x , {x | x ≤ 4 } .
The charge per order = $5 .
Cost of each item = $2
Cost of x items = 2x
Total cost for the order = 5 + 2x
Function to represent this situation : f(x) = 5 + 2x
Now it is given that the maximum of 4 items can be ordered.
Domain: {1,2,3,4}
At x = 1 , f(x) = $7
At x = 2 , f(x) = $9
At x = 3 , f(x) = $11
At x = 4 , f(x) = $13
Range of the function: {7,9,11,13}
A rule is referred to as a function if it produces a distinct result for each input x. In mathematics, a function is represented by a mapping or transformation.
The set of all potential values that can be passed into a function while it is specified is known as the domain. The entire set of values that the function's output is capable of creating is referred to as the "range."
The range of potential values for a function's outputs is known as the co-domain.
