Read each question carefully and provide your answers in the space provided. For questions involving slope fields, draw tangent line segments at the indicated points or sketch solution curves as directed.
1. A slope field (or a direction field) is a graphical representation of the of a first-order differential equation.
2. Each line segment in a slope field represents the of the solution curve that passes through that point.
3. If a slope field has segments that are all horizontal along a certain line, it indicates that the derivative dy/dx is along that line.
4. Consider the differential equation dy/dx = x + y. Sketch the slope field for this differential equation at the following points:
a) (-1, 1)
b) (0, 0)
c) (1, -1)
d) (1, 1)
5. Which of the following differential equations corresponds to the given slope field?
dy/dx = x
dy/dx = y
dy/dx = -x
dy/dx = -y
6. A slope field can be used to sketch particular solutions to a differential equation if an initial condition is given.
True
False
7. For the differential equation dy/dx = x^2, all tangent segments on the y-axis will be horizontal.
True
False
8. Given the slope field below, sketch the solution curve that passes through the point (0, 1).
9. Explain how the slope field of dy/dx = y differs from the slope field of dy/dx = -y. Describe the general behavior of solution curves for each.
