A linear equation
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
Draw a graph of a given curve in the xoy plane. Now draw a vertical line so that it cuts the graph. If the vertical line cuts the graph in more than one ordinate then given graph is not a function. If it cuts the graph at a single ordinate such a graph is a function.(is called vertical line test)
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
take a vertical line, if another line intersects that vertical line at 2 points, then it is a function.In other words,a graph represents a function if each vertical line meets its graph in a unique point.
A sliding test. The vertical line can meet the graph at at most one point.
A monotonic, or one-to-one function.
linear function
A linear function.
A linear function.
A linear function is a function whose graph is a straight line.
It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.
Yes the graph of a function can be a vertical or a horizontal line
Yes the graph of a function can be a vertical or a horizontal line
LOTS- cubic - quadratics - reciprocal - hyperbola - trigonometric - and more
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
A differentiable function, possibly - to distinguish it from one whose graph is a kinked curve.
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
