What reflects across the x-axis?
If a function reflects along the x-axis, that indicates that it has both negative and positive solutions. For example, y = x2 reflects along the x-axis because x2 = -x2. In general, a function will reflect along the x-axis if f(x) = f(-x).
What is intercept in a graph?
Wherever a given function crosses either the x-axis (which would be an x-axis intercept), or where the given function crosses the y-axis (which would be a y-axis intercept). Functions sometimes have more than one intercept of either axis, so be careful to check for those.
Does a power function cross the x-axis?
Maybe it does and maybe it doesn't.Some do: y = x2 - 1 (crosses the x-axis in 2 places)and some don't: y = x2 + 1
Which comes first x axis or the y axis?
The x-axis comes first. because x comes before y.
Is a line with undefined slope the graph of a function?
This is not a function. To be a function, there must be a one to one relationship between the independent variable (usually represented by the horizontal or x axis) and the dependent variable (usually represented by the vertical or y axis). A line with undefined slope is a vertical line, so there are an infinite number of possibilities for y and only one possible value of x, so this is not a function.
What a stage manipulator knobs to a microscope?
Stage manipulator knobs on a microscope are used to move the slide horizontally (x-axis) and vertically (y-axis) to position the specimen for viewing. They allow for precise control and adjustment of the position of the specimen on the stage.
What does the mechanical stage knobs on a microscope do?
The mechanical stage knobs on a microscope are used to move the slide left/right (x-axis) and up/down (y-axis) in a controlled manner. This helps in positioning the slide to view different areas under the objective lens without having to touch the slide directly, which could disturb the sample.
What is the function of the mechanical stage of a microscope?
The mechanical stage of a microscope holds the specimen and allows for precise movement in all directions (X and Y axes) using mechanical controls. This enables the user to easily scan the entire specimen and make precise adjustments for focusing and examination.
What is a function that is symmetric with respect to the x axis?
The only function that can be symmetric about the x-axis is the x-axis itself. For each value of x a function, f(x), can have at most one value for f(x). Otherwise it is a mapping or relationship but not a function.
How do you move the slide when focusing?
To move the slide when focusing, use the mechanical stage controls on the microscope. These typically include knobs or buttons that allow you to move the slide horizontally (X-axis) and vertically (Y-axis). Slowly adjust the controls to bring the area of interest into focus.
What is the reflection through an x axis?
All y-values in the function are multiplied by -1. This function is 'flipped' over the x-axis.
The horizontal asymptote for exponential function is?
The graph of an exponential function f(x) = bx approaches, but does not cross the x-axis. The x-axis is a horizontal asymptote.
What is x intercept defined as?
The x-intercept is the point at which a graph or function intersects the x-axis. It is the value of x when y is equal to zero on the graph.
What reflects across the x-axis?
If a function reflects along the x-axis, that indicates that it has both negative and positive solutions. For example, y = x2 reflects along the x-axis because x2 = -x2. In general, a function will reflect along the x-axis if f(x) = f(-x).
What is the effect on a graph when you multiply a function by -1?
When a function is multiplied by -1 its graph is reflected in the x-axis.
Where does a function equal zero?
If you set a function equal to zero and solve for x, then you are finding where the function crosses the x-axis.
What is an example of an x -intercept?
An x-intercept is the point where a function intersects the x-axis on a Cartesian coordinate plane. For example, if the graph of a parabola is plotted and the graph intersects the x-axis on the coordinate plane, the point(s) where the graph intersects the x-axis are the x-intercepts for that function.
