Guided Notes
Key concepts students will learn:
- •
The graph of f(x) = -3x² + 8 will be a parabola because the highest degree term is x².
- •
Because the coefficient on the x² term is negative, the parabola will open downwards.
- •
When x = 0, f(x) = 8, so the y-intercept, where x = 0, is at the point (0, 8).
