How to Find Intercepts with Factoring & Quadratic Formula. X-Intercept (Definition) Thex-interceptis the point where the graph of the plotted line crosses the x-axis. On the graph below, the plotted line crosses the x-axis at x = 5. ...
If it is an equation or a quadratic function the method is different. How to find the x-intercept of a function or equation requires setting the value of y to zero and calculating the answer(s) for x. The x-intercept formula for a linear equation when in the form Ax + By = C, ...
Apply the quadratic formula, which gives the roots p and q. Then, the intercept form of the parabola is y = a(x - p)(x - q) What is intercept form? A quadratic function has general form y = ax^2 + bx + c. The intercept form is y = a(x - p)(x - q), where p and ...
Determine the x-intercept(s) of the following function:f(x)=x2−8x−7. Question: f(x)=x2−8x−7 Intercepts of a Quadratic Function: The intercepts are the points with find on the axes of the Cartesian plane. That is, they are the points where the graph of a function inte...
Answer to: Write an equation for the quadratic with x-intercepts (-3, 0) and (2, 0) and y-intercept (0, -3). By signing up, you'll get thousands of...
Can I use the quadratic formula to find the x-intercept(s) of a cubic function? No, the quadratic formula can only be used to find the solutions for quadratic equations. To find the x-intercept(s) of a cubic function, you need to factor or use the Rational Root Theorem and syn...
