To determine the equation that corresponds to the graphed function, we need to analyze the characteristics of the graph, such as its slope, intercepts, and overall shape. Often, functions can be linear, quadratic, exponential, or of another type.
Once we identify these features, we can formulate a mathematical equation that accurately describes the graph. For example, if the graph shows a straight line with a certain slope and y-intercept, we can use the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. If the graph is a parabola, we might use the standard form of a quadratic equation, y = ax^2 + bx + c.
By closely inspecting the graph and substituting points from the graph into the identified equation form, we can confirm which equation best matches the graphed function.
