Quick Graphing Differential Equations, calculus homework help

Sketch the equation in the first image that is circled using the Wolfram Alpha program. Sketch the graph for all parameters (there are five parameters so it should be five graphs). Be sure to put (f) in the x-axis and then the parameters in the y-axis. Use small values for alpha. Use the other files/graphs to give you an example of graphs that should be very similar to what you must do. Thanks!

When you are finished, include graphs in a Word document or PDF. Please also show your work/take screen shots of the equations you input into the Wolfram Alpha Program
