Answer:
The graph is not a function of x because the line x=0 intersects the graph at two points
Step-by-step explanation:
For any function of x, x can only map to one point. What this means is that for every x value, it only results in one y value. If you can input x into the relation's equation and get two outputs, the relation is not a function.
We can check if an x value maps to two points by using a vertical line, such as x=0, and if it crosses the relation at two points, the relation is not a function.
Since x=0 crosses the line at two points, it means that this relation is not a function.
Hello!
To solve this you use the equation to find the surface area of a cylinder

SA is surface area
r is radius
h is height
Put in the values you know and 3.14 for pi
SA = 2 * 3.14 * 5 * 29 + 2 * 3.14 * 5^2
SA = 1067.6
The answer is A)1,067.6ft squared
Hope this helps!
