Answer:
c)
Step-by-step explanation:
Hi there!
A function, when it comes to discussing the degree of a polynomial one. We classify them accordingly to the highest exponent.
f(x)=-3x+2 (1st degree since -3x=-3x¹)
f(x)=0x² +3x-3 well, 0x²=0 then f(x)=0x² +3x-3=f(x)=3x-3 (1st degree Linear function with b≠ 0)
f(x) =-7x²-x+2 (2nd degree -Quadratic Function)
f(x)=2x³+2x²-4 (3rd degree -Cubic Function)
So it's the third one from top to bottom, or c) f(x)=-7x²-x+2
