Homework Statement
Consider the differential equation dy/dx = 2y-4x
a. Find the value of b for which y=2x+b is a solution to the given differential equation
b.Let g be the function that satisfies the given differential equation with the initial condition g(0)=0. Does the graph of g have a local extremum at the point (0,0) ? If so, is the point a local maximum or minimum
Homework Equations
integration, derivative
The Attempt at a Solution
a. So I choose point (1,0) and plug in y=2x+b and solve for b=1. Then I have y=2x+1. AM I right ? It seems too easy to be right. Is it harder than I thought ?
b. So do I have to integrate ? I found that (0,0) is a critical point. How do I move on ?
