What is a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Given,
The function is
[tex]f(x) = - x^2 + 2[/tex]
f(2-5) = f(-3)
= [tex]-(-3)^2 + 2\\[/tex]
= -9 + 2
= -7
The value of f(2-5) is -7
