Describe the possible echelon forms of the standard matrix for a linear transformation t where t: set of real numbers is onto.

Which graph corresponds to the function f(x) = x2 + 4x – 1?

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
