- A.4
- B.3
- C.5
- D.6
Answer: C. 5
The degree is the highest power of x with a non-zero coefficient. In 3x^5 + 2x^3 - 7x + 4 the greatest power present is 5, so the degree is 5.
Q2. A coding club represents a cost curve by the polynomial 2x^4 - 5x^2 + 1; what degree does it have?
- A.5
- B.4
- C.2
- D.3
Answer: B. 4
The degree is the highest power of x with a non-zero coefficient. In 2x^4 - 5x^2 + 1 the greatest power present is 4, so the degree is 4.
Q3. During a maths quiz the host reads out the polynomial 6x^3 + 1x^2 - 2x; what is its degree?
- A.4
- B.3
- C.2
- D.101
Answer: B. 3
The degree is the highest power of x with a non-zero coefficient. In 6x^3 + 1x^2 - 2x the greatest power present is 3, so the degree is 3.
