Key Concepts
The graph of every quadratic function is a U shaped curve called a parabola. The vertex of the parabola is its lowest (or highest) point and indicates where the curve changes direction.
The graph of the parent function $f(x) = x^2$ is a parabola that opens upward with its vertex at the origin $(0, 0)$. The graph of $f(x) = x^2 + 3$ is a parabola that opens downward, with its vertex at $(0, 3)$. For $f(x) = (x 4)^2$, the graph is a parabola shifted right, with its vertex at $(4, 0)$.
Every quadratic function graph is a 'U' shaped curve called a parabola! It can open upwards like a smile or downwards like a frown. The most important spot is the vertex, the absolute bottom or top of the curve. It's the turning point where the whole graph changes direction, giving it that perfect, cool symmetry.

Why is Parabola important for Grade 10 students?
Ever wonder what makes a parabola smile or frown? It's all about the sign of the number in front of the term! Think of it like this: a positive sign is like a happy face, so the parabola opens upward (a smile 😊). A negative sign is like a sad face, so it opens downward (a frown 😞). This number...
