How to find f (x) on a graph
Answers
Answer:
bottom of the bar graph is called x axis
Answer:
The most common graphs name the input value xx and the output value yy, and we say yy is a function of xx, or y=f(x)y=f(x) when the function is named ff. The graph of the function is the set of all points (x,y)(x,y) in the plane that satisfies the equation y=f(x)y=f(x). If the function is defined for only a few input values, then the graph of the function is only a few points, where the x-coordinate of each point is an input value and the y-coordinate of each point is the corresponding output value. For example, the black dots on the graph in the graph below tell us that f(0)=2f(0)=2 and f(6)=1f(6)=1. However, the set of all points (x,y)(x,y) satisfying y=f(x)y=f(x) is a curve. The curve shown includes (0,2)(0,2) and (6,1)(6,1) because the curve passes through those points.
