How to find the y-intercept of a quadratic function?
The x-intercept of a line is that point where it cuts the x-axis of the graph, and the y-intercept of a line is that point where it cuts the y-axis of the graph.
Answer: To find the y-intercept of a line, we substitute x = 0 in the equation and find the corresponding value of y.
Let us proceed step by step.
Explanation:
There are few steps to determine the y-intercept of a quadratic function.
- Step 1: Put the value of x as 0.
- Step 2: Solve the equation and get the value of y.
- Step 3: Write y-intercept as (0, y1) and (0, y2).
Let's understand the problem with the help of an example.
Let's find the x-intercepts of y = x2 - 5x + 6
To find the x-intercept, put y = 0.
Hence, x2 - 5x + 6 = y
Substituting x as 0 we get,
y = 0 - 0 + 6
y = 6
The y-intercepts of y = x2 - 5x + 6 is (0, 6)
Hence, to find the y-intercept of a line, we substitute x = 0 in the equation and find the corresponding value of y.
