C. Domain
D. Range

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

Solve the inequality and graph 6j - 7 < 5

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
