Answer:
1. D
2. E
3. C
Step-by-step explanation:
f(x)=(5x³-x²-3x+9)+(3x²-x-7)-(3x³+x²-4)
f(x)=(5x³-x²-3x+9)+(3x²-x-7)+(-3x³-x²+4)
f(x)=(2x³-x²-3x+9)+(2x²-x-3)
f(x)=2x³+x²-4x+6
1. D (the degree is the largest value of an exponent)
2. E (the constant term is the number without a variable)
3. C (the leading coefficient is the coefficient of the largest variable exponent in the value)
