Answer:
-131
Step-by-step explanation:

f(x) = –2x^3+ 3x – 6
f(x) = -2*-5^3+3*5-6
When a number is next to a variable multiply so you problem really is 2(?)=60
With polynomials the degree is the highest power x or whatever the variable is raised to. In this case, the degree is 3 since the highest power x is raised to is x^3
The correct answer should be :
Option 3 :
