Choose the representations or descriptions that model the relation provided in each item. For each relation, select all situations that apply. x -2 0 2 4
f(x) 4 0 4 16

f(x) = -2x

f(x) = x2

The relation is a function.

The relation is not a function.

domain: {-2, 0, 2, 4}

f(4)= -2

Read the equations in the table below. then drag a description of the situation and a table to represent each equation. indicate whether each of the relationships is proportional or non-proportional.

Write an expression that has three terms and simplifies to 4x - 7. identify the coefficient(s) and constant(s) in your expression

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
