Answer:
Function:
Not a function:
Step-by-step explanation:
In order to determine whether a graph is a graph of a function or not, you simply look for the ones that do not give two or more y for every x. In other words, imagine a vertical line going from left to right and ask yourself: how many times does the line cross the graph? If you find even a single x which gives two y, the graph is not a function. For examples take a look at the sketches i drew ;)

Answer:
The answer is 9.4 cm.
Step-by-step explanation:
To solve for the circumference of the circle, use the circumference formula, which is C = 2
.
Next, in the problem, the circle has a diameter measure but no radius measure. To find the radius of this circle, divide the diameter (3 cm) by 2, and it will equal 1.5 cm. The radius is being divided by 2 because the radius of any circle is equal to half the diameter of the circle.
Then, plug in the information given from the problem into the formula, and the formula will look like C = (2) () (1.5 cm).
Finally, solve the equation, and the answer is 9.4 cm.
