Final answer:
To design a parabolic section of a roller coaster, one can find the vertex of the parabola h(x) = ax^2 + bx + c using the vertex formula and then determine the axis of symmetry, which is critical for safety and design.
Step-by-step explanation:
The question concerns the design of the second part of a roller coaster and involves finding the vertex and the equation for the axis of symmetry of a parabola represented by h(x) = ax2 + bx + c. The vertex of a parabola in this form can be found using the formula -b/(2a) for the x-coordinate, and then substituting this back into the equation to find the y-coordinate of the vertex. The axis of symmetry can be represented by the equation x = -b/(2a). In designing a coaster, these elements are crucial for ensuring the safety and proper functioning of the ride.
To illustrate, if a parabola is given by h(x) = 2x2 - 4x + 6, the vertex can be calculated as follows: The x-coordinate of the vertex is -(-4)/(2*2) = 1, and substituting x = 1 into h(x) gives us the y-coordinate: h(1) = 2(1)2 - 4(1) + 6 = 4. Therefore, the vertex is at (1, 4), and the axis of symmetry is the line x = 1.
