Graph the inequality

Explanation of Solution
Given:
The inequality:
Concept Used:
To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (= or =), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.
For = and <, the arrow points down to the left.
For = and >, the arrow points up to the right.
Calculation:
1) Draw a number line. 2) Put either an open circle or a closed dot above the number given. For = and = , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution
A closed, or shaded, circle is used to represent the inequalities greater than or equal to (
An open circle is used for greater than (>) or less than (<). The point is not part of the solution. The graph then extends endlessly in one direction.
For = and <, the arrow points down to the left.

- Suppose that f(x, y, z) = (x − 2)² + (y – 2)² + (z − 2)² with 0 < x, y, z and x+y+z≤ 10. 1. The critical point of f(x, y, z) is at (a, b, c). Then a = b = C = 2. Absolute minimum of f(x, y, z) is and the absolute maximum isarrow_forwardThe spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
