1. **State the problem:** We want to understand how to solve or analyze the function $y=(x-1)^2 + 2$ on a graph.
2. **Formula and explanation:** This is a quadratic function in vertex form: $$y = (x-h)^2 + k$$ where $(h,k)$ is the vertex of the parabola.
3. **Identify the vertex:** Here, $h=1$ and $k=2$, so the vertex is at the point $(1,2)$.
4. **Shape and direction:** Since the coefficient of the squared term is positive (1), the parabola opens upwards.
5. **Axis of symmetry:** The vertical line $x=1$ is the axis of symmetry.
6. **Find y-intercept:** Set $x=0$, then $$y = (0-1)^2 + 2 = 1 + 2 = 3.$$ So the graph crosses the y-axis at $(0,3)$.
7. **Find x-intercepts:** Set $y=0$ and solve for $x$:
$$0 = (x-1)^2 + 2$$
$$ (x-1)^2 = -2$$
Since the square of a real number cannot be negative, there are no real x-intercepts.
8. **Summary:** The parabola has vertex at $(1,2)$, opens upwards, crosses y-axis at $(0,3)$, and has no real x-intercepts.
This analysis helps you graph the function and understand its behavior.
