- The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
Step-by-step explanation:
Step 1: Define
f(x) = x² - 8x + 15
Step 2: Find y-intercept
- Substitute x = 0: f(0) = 0² - 8(0) + 15
- Exponents: f(0) = 0 - 8(0) + 15
- Multiply: f(0) = 0 + 15
- Add: f(0) = 15
- Rewrite: (0, 15)
