Apply Euler's method twice to approximate the solution to the initial value problem on the first with step size h = 0.25, then with step size h=0.1. Compare the interval 0, [0.12]. 1 three-decimal-place values of the two approximations at x = - () 2 2 actual solution. y' = -3xy, y(0) = 7, y(x) = 7 e-x with the value of y of the
