Graph represents a function
Use the vertical line test to determine whether or not a graph represents a function. If we want to check whether the graph is a function or not we use the concept called vertical line test.

Recognize functions from graphs.
. A vertical line includes all points with a particular x value. A coordinate plane with a line passing through -1 -4 0 0 and 1 4 By verification we have. To graph a linear function f x mx b we can use its slope m and the y-intercept b.
So there are two different y -values associated to x 1. If a vertical line is moved across the graph and at any time touches the graph at only one. The y value of a point where a vertical line intersects a graph.
Math Algebra 1 Functions Recognizing functions. In other words it shows where the values of those variables lie on the same axis. The graph does NOT represent a function because it is possible to draw a vertical line that intersects the graph more than once.
What is the function rule for the graph. Recognizing functions from table. This contradicts the phrase in your answer.
A curve drawn in a graph represents a function if every vertical line intersects the curve in at most one point. Y 4x 4 -4 4x. Its slope is m.
The process is explained again by graphing the same linear function f x 3x 5. A graph represents a function if and only if every input generates a single output. The graph of a function is a visual representation of the relationship between two variables.
Graph of the function is the option. O The graph does NOT represent a function. Recognize functions from tables.
If you draw a vertical line through x 1 that line hits two points on the curve. The equation of the graph is in the form y kx where. If a curve graph represents a function then every point on the curve satisfies the function.
To determine whether the given graph represents a function or Q. Recognizing functions from verbal description. Recognizing functions from graph.
Consider a line passes through two points with coordinates x1y1 and x2y2. Graphing functions is drawing the curve that represents the function on the coordinate plane. Does a vertical line represent a function.
Can be used to determine whether a graph represents a function. The graph of a function f is the graph of the equation y fleft x right That is it is the set of all points left xfleft x right right So the function rule can be. HOW TO DFETERMINE WHETHER THE GRAPH IS A FUNCTION.
Take a vertical line if another line intersects that vertical line at 2 points then it is a functionIn other wordsa graph represents a function if each vertical line. If the vertical line drawn. Equation of line is y - -4 4 x - -1 4x 4.
Is The Function Even Odd Or Neither Use The Graph To Decide Graphing Odds Rotational Symmetry
