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

The table represents a function. what is f(-2)? a.-3 b. -1 c.1 d.3

Which inequality statement describes the two numbers on a number line? "? 7 and a number 5 units to the right of ? 7"
