A

Consider the point \(A = [-1,-3]\) and the function \(f(x) = \frac{k} {x}\) with a nonzero real parameter \(k\in \mathbb{R}\setminus \{0\}\). Identify the value of the parameter \(k\) which ensures that the point \(A\) is on the graph of \(f\).

Given the function \(f(x) = -\frac{8} {x}\), evaluate \(f(-4)\).

Given the functions \(f(x) = -\frac{3} {x}\) and \(g(x) = 6\), solve \(f(x) = g(x)\).

Given the linear function \(f(x) = -2x + 3\), evaluate \(f(2) + f(-2)\).
