Concept explainers
To find: The standard form of the quadratic function and the graph for it, also identify the graph, vertex axis of symmetry and x intercepts.
Answer to Problem 23E
The quadratic function in the standard form is
Explanation of Solution
Given:
The given function is
Calculation:
Consider the quadratic function is,
The vertex of the above parabola for the standard form
Consider the given equation is,
From the above equation the vertex of the function
Thus, the axis of symmetry of the graph is
To find the
Consider the point for
Consider the point for
The value of the x intercept is not a real number so it does not have any intercept on the x axis.
The sign of the coefficient
The graph is shown in Figure 1

Suppose that U(x, y, z) = x² + y²+ z² represents the temperature of a 3-dimensional solid object at any point (x, y, z). Then F(x, y, z) = -KVU (x, y, z) represents the heat flow at (x, y, z) where K > 0 is called the conductivity constant and the negative sign indicates that the heat moves from higher temperature region into lower temperature region. Answer the following questions. (A) [90%] Compute the inward heat flux (i.e., the inward flux of F) across the surface z = 1 - x² - y². (B) [10%] Use the differential operator(s) to determine if the heat flow is rotational or irrotational.arrow_forward
