Find the y intercept of a function calculator

Since the y-intercept always has a corresponding x-value of 0, replace x with 0 in the equation and solve for y. On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.

Here are some examples of y intercepts. The y-intercept of y = 5x² + 2 is, (0, 2) because when we substitute x = 0, we get y = 5(0)² + 2 = 2. The y-intercept of y = -5e^x is (0, -5) because when we substitute x = 0, we get y = -5e⁰ = -5.
