Answer:
f(4) = - 5
Step-by-step explanation:
Using the recursive formula and f(1) = 7, then
f(2) = f(1) - 4 = 7 - 4 = 3
f(3) = f(2) - 4 = 3 - 4 = - 1
f(4) = f(3) - 4 = - 1 - 4 = - 5
The value of function f(4) will be equal to - 5.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Using the recursive formula and f(1) = 7, then the value of f(4) will be calculated as below:-
f(2) = f(1) - 4 = 7 - 4 = 3
f(3) = f(2) - 4 = 3 - 4 = - 1
f(4) = f(3) - 4 = - 1 - 4 = - 5
Therefore, the value of function f(4) will be equal to - 5.
