In mathematics, the y –intercept of a function, f(x) , is the y -value of the point where the graph of f(x) crosses the y -axis. This occurs where x=0 , so we can find the y –intercept of a function, f(x) , by plugging x=0 into the function, which is equivalent to calculating f(0) .
What is the Y intercept of the function f X?, Explanation: Note that f(x) is equivalent to y . The y–intercept is the value on the Y-axis where the function crosses the Y-axis. Since the Y-axis is the collection of points where x=0 , it follows that the y–intercept is the value of the function when x=0 .
Furthermore, What are the x and y-intercepts of f X?, x- and y–Intercepts. The graphical concept of x- and y–intercepts is pretty simple. The x–intercepts are where the graph crosses the x-axis, and the y–intercepts are where the graph crosses the y-axis. The problems start when we try to deal with intercepts algebraically.
Finally, How do you find the Y intercept in a function?,

Frequently Asked Question:
What is Y intercept of the function?
The y–intercepts are points where the graph of a function or an equation crosses or “touches” the y-axis of the Cartesian Plane. You may think of this as a point with x-value of zero. To find the y–intercepts of an equation, let x = 0 x = 0 x=0 then solve for y.
What is the Y intercept of each function?
The y–intercepts are points where the graph of a function or an equation crosses or “touches” the y-axis of the Cartesian Plane. You may think of this as a point with x-value of zero. To find the y–intercepts of an equation, let x = 0 x = 0 x=0 then solve for y.
What is meant by Y intercept?
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y–intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
How do you find the Y intercept in a quadratic function?
To find the y–intercept let x = 0 and solve for y. Step 3: Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).

How do you find the Y intercept when given two points?
Steps
- Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)
- Substitute the slope(m) in the slope-intercept form of the equation.
- Substitute either point into the equation. You can use either (3,5) or(6,11).
- Solve for b, which is the y-intercept of the line.
- Substitute b, into the equation.
