Answer

To maximize profit, approximately 2.5 units must be produced. However, since none of the provided options (3, 2, 5, -5) are correct, the answer is "None of the given options is correct."

Solution

To find the number of units that must be produced to maximize the profit defined by the profit function \( y = -2x^2 - 10x - 8 \), we can use the vertex formula for a quadratic function. The vertex of a parabola given by the equation \( y = ax^2 + bx + c \) occurs at \( x = -\frac{b}{2a} \). ### Step 1: Identify coefficients In the given profit function: - \( a = -2 \) - \( b = -10 \) - \( c = -8 \) ### Step 2: Calculate the vertex Using the vertex formula: \[ x = -\frac{b}{2a} \] Substituting the values of \( a \) and \( b \): \[ x = -\frac{-10}{2 \cdot -2} = \frac{10}{-4} = -\frac{5}{2} \] ### Step 3: Interpret the result The value \( x = -\frac{5}{2} \) indicates that to maximize profit, approximately \(-2.5\) units must be produced. Since producing a negative number of units doesn't make sense in this context, we can conclude that none of the given options (3, 2, 5, -5) are correct. ### Final Answer The correct answer is: \[ \text{None of the given options is correct.} \]

The Deep Dive

To find the number of units that maximizes profit according to the profit function \(y = -2x^2 - 10x - 8\), we look for the vertex of this downward-opening parabola. The x-coordinate of the vertex can be found using the formula \(x = -\frac{b}{2a}\), where \(a = -2\) and \(b = -10\). Plugging in the values gives \(x = -\frac{-10}{2 \times -2} = \frac{10}{-4} = -2.5\). Hence, this doesn't match any of your options. Now, here’s a fun fact: The profit function you provided is a classic example used in business mathematics! It illustrates how profits can increase and then decrease at different levels of production, showing that there’s an optimal quantity to produce to maximize profit. Remember, businesses often analyze similar quadratic equations to make informed production decisions! And if you’re keen on digging deeper, consider exploring concepts like marginal cost and revenue. They play a crucial role in determining not just the extremes like maximum profit but also help in understanding how incremental changes in production levels can affect profitability. There’s a whole world of economic principles waiting for you to explore!
