Circle : A circle is a two-dimensional shape. The boundary of a circle is a set of points that has the same distance (the radius) from the center of the circle.
Constant : Constant is another word for a fixed number that is mainly used in the context of expressions or functions like $f(x)=c$ that are equal to the same number irrespective of any variable.
Function : A function is a mapping in which every element in one set is mapped to exactly one element of a second set. Most often the mapping is described using a rule. For example the function $f(x)=x+1$ maps 2 to 3 and -1 to 0.
Graph : The graph of a function is the set of points $\{(x,f(x))\}$ that can be blotted in a coordinate system.
Horizontal : In the direction from left to right.
Line : A line AB is a one-dimensional shape that includes the points A and B, all the points on the line segment in between A and B and all the points of the straight extension of the line segment beyond A and B. A line does not have an endpoint.
Map : In mathematics mapping means assigning exactly one value to an object. A function maps every $x$ to exactly one $y.$
Vertical : In the direction from down to up.
Select all statements that are true about functions.
The above picture shows that graph of the function $f(x)=$_______.
Counterexample : A counterexample to a statement of the form 'all objects of type x have property y' is an object of type x that does not have property y. A counterexample to a statement shows that the statement is not true in general. For example the number 3 is a counterexample to the statement that all numbers are even.
Root : A root is a solution to an equation of the $f(x)=0$ where $f$ is a function or expression. For example the function $f(x)=x-1$ has the root $x=1.$
