Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

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

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4
