Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

What is the solution to the equation? k/6.4=8.7 2.3 5.568 15.1 55.68

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
