Determine the domain and the range of the function.f(x) = x2 + 10x + 25
A. domain: all real numbers range: {y|y ? 25} B. domain: {x|x ? -5} range: {y|y ? 0} C. domain: all real numbers range: {y|y ? 0} D. domain: {x|x ? 5} range: {y|y ? 0}
x? = x(0.05 ? 0.002x ? 0.0015y) , y? = y (0.03? 0.0025x ? 0.0003y) , x (0) = 3, y (0) = 5
For the systems of differential equations, use Euler’s method with ?x = 2 to plot the trajectory of x and y to plot the trajectory for 0 ? t ? 500
