Math Problem Statement

uppose the function fsxd 5 50 2 9x 1 x4 y30 describes a physical situation that makes sense only for whole numbers between 0 and 10. For what value of x does f reach a minimum, and what is the minimum value? (Suggestion: We suggest beginning with a table starting at 0 with a table increment of 1 and then panning further down the table.)

Solution

It seems like the function you're referring to is incomplete or has some typographical errors. However, I can reconstruct the problem and solve it step by step. Based on what you’ve written, I believe the function might be similar to this:

f(x)=5x250x+2f(x) = 5x^2 - 50x + 2

This is a quadratic function, which typically represents a parabola. Since the coefficient of x2x^2 is positive (5), the parabola opens upwards, meaning that it has a minimum point.

Let's solve for the value of xx where f(x)f(x) reaches a minimum and compute the corresponding minimum value.

Step 1: Find the vertex of the parabola

For a quadratic function in the form:

f(x)=ax2+bx+cf(x) = ax^2 + bx + c

The xx-coordinate of the vertex, which gives the minimum (or maximum) point for the parabola, is found using the formula:

x=b2ax = -\frac{b}{2a}

For our function f(x)=5x250x+2f(x) = 5x^2 - 50x + 2, we have:

  • a=5a = 5
  • b=50b = -50

Substitute these values into the formula:

x=502(5)=5010=5x = -\frac{-50}{2(5)} = \frac{50}{10} = 5

Thus, the value of xx where the function reaches its minimum is x=5x = 5.

Step 2: Find the minimum value of the function

Now, substitute x=5x = 5 back into the original function to find the minimum value:

f(5)=5(5)250(5)+2f(5) = 5(5)^2 - 50(5) + 2 f(5)=5(25)250+2f(5) = 5(25) - 250 + 2 f(5)=125250+2=123f(5) = 125 - 250 + 2 = -123

Conclusion:

  • The function reaches its minimum value at x=5x = 5.
  • The minimum value of the function is 123-123.

Here are 5 related questions for further exploration:

  1. What does the vertex of a quadratic function represent in real-world problems?
  2. How can we determine if a quadratic function opens upwards or downwards?
  3. What is the axis of symmetry in a quadratic function, and how is it related to the vertex?
  4. How can the discriminant be used to analyze the nature of the roots of a quadratic equation?
  5. What other methods can be used to find the minimum value of a quadratic function?

Tip: For any quadratic function, the vertex is always the critical point, and its coordinates can be found easily using b2a-\frac{b}{2a}. This gives you valuable insights into the function's behavior.
