Not quite.
You can use a vertical line test on the graph of the inverse mapping,
OR
you can use a horizontal line test on the original graph.
The horizontal line test is used in the same way.
Looking at the graph of the function can give you a good idea. However, to actually prove that it is even or odd may be more complicated. Using the definition of "even" and "odd", for an even function, you have to prove that f(x) = f(-x) for all values of "x"; and for an odd function, you have to prove that f(x) = -f(-x) for all values of "x".
· whether it is linear, quadratic or exponential · whether it has an upper or lower bound · whether it has a minimum or a maximum value · whether it is constant, decreasing or increasing
You can compute that once you know specific values for variables x, and n. exp n is the exponential function, or antilog to base e. On scientific calculators, you would usually press keys like "inverse" "ln", or "shift" "ln", or something similar. To check whether you did the calculation correctly, exp 1 should show you approximately 2.718.
base
That is a function defined as: f(x) = -1 if x is negative f(x) = 0 if x is zero f(x) = 1 if x is positive In other words, a function that basically distinguishes whether the input is positive, negative, or zero.

The horizontal line test is used to determine whether a function is one-to-one and if it had a inverse.
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
To determine whether a graph represents a function, you can use the vertical line test. If any vertical line drawn on the graph intersects the curve at more than one point, the graph does not represent a function. This is because a function must assign exactly one output value for each input value. If every vertical line intersects the graph at most once, then it is a function.
Draw a vertical line if the line hits more than one point on the graph then it is not a function.
A vertical line test can be used to determine whether a graph is a function or not. If a vertical line intersects the graph more than once, then the graph is not a function.
A vertical line can be used to test whether or not a graph is a function.
A function can only have one output for any given input. This means that any x value you choose cannot have multiple corresponding y values. The vertical line test involves looking at a graph and drawing vertical lines over it. If any of the vertical lines you have drawn touch the graph of the function more than once, then the graph does not represent a function.
To determine if a relation is a function, check whether each input (or x-value) corresponds to exactly one output (or y-value). This can be done by examining ordered pairs or a graph: if any x-value maps to multiple y-values, the relation is not a function. In a graph, if a vertical line intersects the curve more than once, the relation fails the vertical line test and is not a function.
To determine if a graph represents a function, you can use the vertical line test. If any vertical line drawn on the graph intersects it at more than one point, then the graph does not represent a function. In contrast, if every vertical line intersects the graph at most once, then it is a function. This test helps ensure that each input (x-value) corresponds to exactly one output (y-value).
Determines whether a given mathematical expression is a function or not.
