Find the wronskian of y_1 = 2x + 3, y_2 = x^2 + 3x, and y_3 = x^2 - 1. use the result to determine if the three functions are linearly independent on (- infinity, infinity). w [2x + 3, x^2 + 3x, x^2 - 1] = are the functions linearly independent on (- infinity, infinity)?

How do i do this activity, is appreciated

What is the area of the trapezoid shown ?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
