Question 4 The integral SA 1-2x dx is not improper improper there is no infinite limit of integration because it equals a finite value the integrand function has a vertical asymptote the integrand function's vertical asymptote lies outside the interval of integration it equals an infinite valueQuestion 5 Consider the differential equation y' it) = 2y- Is each of the following a solution to y! (t) = 2y? Select true or false for each proposed solution. false _ I'. ' y 23 l true vl _ 2t1 false v' I 1,\" _ B l true _ 1 -2t' Select v' - e y 2 true false Question 6 Consider the differential equation dy dt =y- t. Is each of the following a solution to + = y -t? Select true or false for each proposed solution. false . y =t+2 true false . y=t+1 true false . y = t+ 1+2et true
