To solve for a we also use the other point at (2, 10). In the given graph the asymptote passes through (0, 2). The value of b in the equation of a hyperbola corresponds to its asymptote. We do not take the negative square root since the exponential function is not defined for negative base. To find a, we substitute the coordinates (2,10) in the equation.
To find the equation of the exponential function curve: Therefore the equation of the parabola or the quadratic function represented by the parabola is. To find the value of a we use the other point A. The y-intercept is also 2 which corresponds to the value of b in the equation. Therefore, the equation of the linear function is f(x) = 4x + 2. In the equation f(x) = ax + b, b is the y-intercept hence the equation is now f(x) = ax + 2. The line passes through (0, 2) hence the y-intercept is 2. You can do this by substituting the coordinates of the two points A and B to the equation. What is the equation of each graph? Determining the Equations of the Graphs of Functionsĭid you notice that all the graphs pass through two points? Well, technically the violet one doesn’t but it’s asymptote does pass through one of the points.ĭid you notice that all the equations have two parameters a and b? This means that all you need to do to find the equations of the line is to solve for the values of a and b. The algebraic representation of the functions are also also given. The figure below shows the graphs of common functions. Here is a problem that involve finding the equation given the graphs of functions – linear, quadratic, exponential, and reciprocal (rational) functions. GPAW version 0.7.In your study of function, the usual activity you do is to graph the function given an equation.
