In the given figure there are 3 graphs
The line represents a linear function

The parabola represents a quadratic function

The third graph which approaches to the negative part o the x-xis is the exponential function

The x-intercept of the line is (-2, 0)
x-intercept means intersect the x-axis at point (-2, 0)
There is only one graph that intersects the x-axis at (-2, 0)
It is the line, the linear function h(x)
The range is between 0 to infinity (0, ∞)
The range is the values of y
There is only one graph that has all values of y over the x-xis
it is f(x) the exponential function
Answer:
The area of the circular ring is 53.73 π sq. yards
Step-by-step explanation:
The diameter of the skating ring = 44 ft
Diameter = 2 x Radius
⇒Radius of the ring = 44 / 2 = 22 ft
Now, 1 ft = 0.333333 yards
⇒22 ft = 22 x 0.333333 yards = 7.3333 yards
Now, Area of the circular Ring = 
or, 
= 53.73 π sq. yards
or, the area of the circular ring is 53.73 π sq. yards
