(1 point) consider the initial value problem ′=4y, y(−1)=−2. find the value of the constant and the exponent so that y= is the solution of this initial value problem. y= (formulas) determine the largest interval of the form < < on which the existence and uniqueness theorem for first order linear differential equations guarantees the existence of a unique solution. (inequalities) what is the actual interval of existence for the solution (from part a)? (inequalities)
