write an expression for the sequence of operations described below
A: –
Concept:
Represent a sequence of operations as a single function f by composing the operations in the given order.
– Expression (example form): If the sequence is: add a, then multiply by b, then subtract c, the expression is f(x) = (x + a) * b – c.
– One clear example: Let a = 3, b = 2, c = 5, and x = 4. Then f(4) = ((4 + 3) * 2) – 5 =
11. – Concept (brief): The final expression is the ordered application of the operations to the input.
– Brief example: With the same a, b, c and x = 0, f(0) = ((0 + 3) * 2) – 5 = 1.
