Answer:
1) -6
2) 7
3) -6
Step-by-step explanation:
p(x) = 5x⁷ - 6x⁵ + 7x - 6
1) The coefficient of x⁵ is the number -6. This is the number by which x⁵ is multiplied.
2) The degree of p(x) is 7. This is the highest power of x that occurs (with a nonzero coefficient).
3) The constant term is -6. Notice that p(x) = 5x⁷ - 6x⁵ + 7x¹ - 6x⁰, so this can also be thought of as the coefficient of x⁰ or the coefficient of 1. This is the term that is constant in the sense that it does not change as x changes.
