1. The problem Q-1 a) asks: If given some values or expressions (not fully provided), find a certain value or expression. Since the full question is not visible, we can illustrate a general approach: Identify the given values or expressions, substitute into the formula or equation, and simplify to find the desired quantity. 2. Q-1 b) asks us to find the zeros of a function. To find zeros of a function $f(x)$, solve the equation $$f(x) = 0.$$ This means finding all values of $x$ that make the function equal to zero. Since the explicit function is not provided, let us assume the function is $f(x) = ax^2 + bx + c$. The zeros can be found using the quadratic formula: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}.$$ Steps to find zeros: 1. Identify coefficients $a$, $b$, and $c$. 2. Calculate the discriminant: $$\Delta = b^2 - 4ac.$$ 3. If $$\Delta \geq 0$$, compute zeros with the formula above. 4. If $$\Delta < 0$$, the function has no real zeros. Because the exact function is not specified, these principles apply generally to polynomial functions. Final answers depend on the specific function provided in the question.
