a. the independent values, or x values

b. a relation where for any given input value there is only one output value

c. a value substituted in for the variable in a function which generates another value (the output)

d. a way of representing how the members of one group are related to the members of another group

e. a group of two numbers written in an order (x, y) so that the first value represents a horizontal position and the second number represents a vertical position

f. a value generated by a function from another value (an input) which was substituted into the function and evaluated
the dependent values, or y values

g. a set of ordered pairs

h. a test to determine if a graph is a function; a vertical line can only go through one point on the graph to be a function

(i really need ) read the story problem, and then answer the questions that follow. gordon works for a graphic design firm and is creating a label for a food truck vendor. the vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. to complete his label, gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches. part a: find the slant height of the cone. the slant height is the distance from the apex, or tip, to the base along the cone’s lateral surface. show your work. part b: find the measure of the angle formed between the base of the cone and a line segment that represents the slant height. part c: imagine two line segments where each represents a slant height of the cone. the segments are on opposite sides of the cone and meet at the apex. find the measurement of the angle formed between the line segments.
