Which graph represents a function? which statement explains why your graph from question 4 is a function? question 5 options: each y value pairs to any x value. it is the graph of a linear equation. each x value pairs to one and only one y value. the solutions to the equation can be written as ordered pairs.

Part 1:

The final graph with upward parabola represent a function because only this curve passes the Vertical Line Test.

Part 2:

Each x value pairs to one and only one y value.

To check whether a graph is function or not we use Vertical Line Test which draws a vertical line. A function must have one output y for each unique value of x.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
