First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.

To find the answer you need to plug in each individual ordered pair matching up the number with the variable. the answer is (6,2) since if you plug it in the equation becomes 2 = 6 - 4, which ends up 2 = 2. since the final equation is true, then (6,2) must be the answer.

domain: (-∞, ∞)range: (-∞, ∞)the relation is a function

step-by-step explanation:

any linear relation with finite slope (that is, something other than x=constant) will be a function with a domain and range of "all real numbers."

further, any odd-degree polynomial will likewise be a function with domain and range of "all real numbers." a linear equation is a polynomial of degree 1, hence of odd degree.
