Equation maker from x and y intercept3/13/2023 ![]() ![]() Is that of f(x) = x 3 shifted 2 units to the right because of the term (x - 2) and reflected on the x axis because of the negative sign in f(x) = - (x - 2) 3. The y intercept is a point on the graph of f. After expansion of f(x), we can see that the leading coefficient (of x 3) is negative, the graph of f is down on the right and up on the left and hence the range of f is the set of all real numbers.Īt x = 2, the graph cuts the x axis.c - The domain of f (x) is the set of all real numbers.Function f has one zero at x = 2 of multiplicity 3 and therefore the graph of f cuts the x axis at x = 2.Use the y intercept, x intercepts and other properties of the graph of to sketch the graph of f.Find all zeros of f and their multiplicity.Since the leading coefficient (of x 3) is positive, the graph of f is up on the right and down on the left and hence the range of f is the set of all real numbers.Īlso since f(-x) = - f(x), function f is odd and its graph is symmetric with respect to the origin (0,0).b - The domain of f (x) is the set of all real numbers.The x intercept are at the points (0, 0).The x coordinates of the x intercepts are the solutions to.Find the x and y intercepts of the graph of f.If the leading coefficient is negative, as x increases f(x) decreases the graph of f is down and as x decreases indefinitely f(x) increases the graph of f is up. If the leading coefficient a is positive, as x increases f(x) increases and the graph of f is up and as x decreases indefinitely f(x) decreases and the graph of f is down. The left hand side behaviour of the graph of the cubic function is as follows: The x intercepts are found by solving the equation The y intercept of the graph of f is given by y = f(0) = d. ![]() The range of f is the set of all real numbers. The domain of this function is the set of all real numbers. ![]() Where a, b, c and d are real numbers and a is not equal to 0. Properties, of these functions, such as domain, range, x and y intercepts, zeros and factorization are used to graph this type of functions. txt file is free by clicking on the export iconĬite as source (bibliography): Y-Intercept on dCode.Graphing Cubic Functions Graphing Cubic FunctionsĪ step by step tutorial on how to determine the properties of the graph of cubic functions and graph them.

With 2 points, can be calculated the equation of the line (see the linear equation calculator) and thus to deduce the y-intercept (see above)įrom the slope coefficient and 1 point (line only) Example: A line of equation y=3x+4 has 4 as y-intercept ![]()
