F(x) = x + 3
g(x) = 2x2 - 4
Find (f ·g)(x).

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

Find the value of x for which line a is parallel to line b

Which property was used to simplify the expression? 3c+9 +4c=3c+4c+9
