Use Euler's method to approximate the solution. Also find the exact solution. Round your answers to four decimal places.Use Euler's method with ?x = 0.5 to approximate y(5) given that 
and y(1) = -1. Also find the exact value of y(5).
A. y(5) ? -0.1949; the exact solution is y(5) = -0.2594 B. y(5) ? -0.1482; the exact solution is y(5) = -0.2224 C. y(5) ? 0.0821; the exact solution is y(5) = -0.1601 D. y(5) ? -0.0879; the exact solution is y(5) = -0.1893
