<span>C.
Each y-value has only one x-value.
y value can have many x-values</span>
The <u>correct answer</u> is:
The function is a one-to-one function.
Explanation:
When an equation is graphed, we use the Vertical Line Test to determine if that equation is a function; if a vertical line hits more than one point anywhere on the graph, the graph is not a function.
This corresponds with the definition of a function: A function is a set of ordered pairs in which each element of the domain (x) is mapped to no more than one element of the range (y). Since every x has no more than one y, there will be no two points hit by the same vertical line.
When we have the graph of a function, to determine if it has an inverse, we use the Horizontal Line Test: if a horizontal line hits more than one point anywhere on the graph, the function does not have an inverse.
This corresponds with the definition of a one-to-one function: A function in which every element of the range (y) is mapped to exactly one element of the domain (x). Since every y has one x, there will be no horizontal line that hits more than one point anywhere on the graph.
Answer: There must be definitely at most n value of x - intercept
Step-by-step explanation: If a polynomial has a value of n degree, then, there must be definitely at most n value of x - intercept.
For instance, The polynomial has a degree of 8, so there are at most 8 x-intercepts and at most 8–1 = 7 turning points.
Answer:
intersection of the y axis
