Determine whether the graph is the graph of a function. two curves are drawn. the first is a curve that starts from a hole at 1,-2 and curves down and then back up towards negative infinity. the second is a horizontal line that starts at the point 1, -1 and continues towards infinity. yes no

  Yes

Step-by-step explanation:

The description does not have the curves overlapping at any point, so there is only one output for each input. That makes the graph be the graph of a function.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
