Quadratic or Not?
📚 Part 1: Multiple Choice
1. Which equation represents a quadratic function?
y = 2x² + 3x − 5
y = 3x + 1
y = x³ − 2x
y = 4/x
2. Which graph description is a quadratic (parabola)?
Smooth U-shaped curve opening upward or downward
Straight line
V-shaped absolute value
Rapidly increasing exponential curve
3. For y = −x² + 2x + 3, the parabola opens:
Upward
Downward
4. Is y = (x − 1)(x + 2) a quadratic function?
Yes
No
✏️ Part 2: Short Answers & Classification
5. Which coefficient in y = ax² + bx + c determines whether the parabola opens up or down?
6. Classify each function below. Write "Quadratic — opens up/down" or "Not quadratic". Use the space provided.
a) y = 0.5x² − 4
b) y = −2x + 7
c) y = x³ − x
7. List two visual features on a graph that help you identify it as quadratic (parabola):
8. Match each equation (left) with the best graph description (right). Draw a line to match.
A. y = x²
B. y = −x² + 4
C. y = 2x
D. y = x³
1. Straight line (constant slope)
2. Parabola opening upward
3. S-shaped cubic curve
4. Parabola opening downward
