Which Is The Graph Of?
In mathematics, the graph of a function is a visual representation of the function. It is a two-dimensional plot of the function’s output values (y-values) as a function of its input values (x-values).
To find the graph of a function, we can use a variety of methods, such as:
- Plotting points: We can plot points on the graph by plugging in different values of x and evaluating the function.
- Using the slope-intercept form: If the function is in slope-intercept form, we can use the slope and y-intercept to find the equation of the line that represents the graph.
- Using the point-slope form: If we know two points on the graph, we can use the point-slope form to find the equation of the line that passes through those points.

Answering Questions About Which Is The Graph Of
To answer questions about which is the graph of a function, we can use the following steps:
- Identify the key features of the graph. What type of curve is it? Are there any asymptotes? Are there any intercepts?
- Consider the type of function that is being represented. What are the characteristics of that type of function?
- Compare the graph to the graphs of known functions. Can you identify any similarities or differences?
Examples
Here are some examples of how to answer questions about which is the graph of a function:
- Which graph represents a function?
To answer this question, we need to identify the key features of the graph. If the graph is a curve that passes through two or more points, then it represents a function. If the graph is a series of unconnected points, then it does not represent a function.
In the following graph, the curve passes through three points. Therefore, the graph represents a function.

To answer this question, we need to identify the key features of the graph. A linear function is a function whose graph is a straight line. The slope of the line can be found by dividing the change in y-values by the change in x-values.
In the following graph, the line has a constant slope. Therefore, the graph represents a linear function.
[Image of a graph of a linear function]- Which graph represents a quadratic function?
To answer this question, we need to identify the key features of the graph. A quadratic function is a function whose graph is a parabola. The parabola is symmetric about its axis of symmetry.
In the following graph, the parabola is symmetric about the x-axis. Therefore, the graph represents a quadratic function.
