(iii)

$f(-3)$

Answer

Explanation

This question involves evaluating a linear function f(x) = 2x - 5 at specific values of x. As mentioned in the textbook context, the function f defined by f(x) = mx + c, x ∈ R, is called a linear function. To find the value of the function at any point, we simply substitute the given value of x into the function definition.
