The value of the expression when w = -5 is -1
Functions and values
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Given the equation in question expressed as;
f(w) = w^2 + 3w − 11
Of the value of w is -5, hence;
f(-5) = (-5)^2 + 3(-5) - 11
f(-5) = 25 - 15 - 11
Simplify the resulting expression
f(-5) = 10 - 11
f(-5) = -1
Hence the value of the expression when w = -5 is -1
