Determine if the equation x - ya = 1 defines y as a function of x.
no. at least one input results in more than one output.
yes. one input results in one output.
no. at least one output results in more than one input.
yes. one output results in one input.

  Yes. One input results in one output.

Step-by-step explanation:

If "A" is not dependent upon x or y, this is a linear equation. Any linear equation in two (or more) variables defines a function.

Yes, this equation defines a function.

__

A function has one output for each input. The appropriate description is the one shown as the Answer.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
