Step-by-step explanation:
f(x) + g(x) = 3x^2 + 2x - 1 + x^2 - 3x + 1
f(x) + g(x) = 4x^2 - x
==================================
f(x) - g(x) = 3x^2 + 2x - 1 - x^2 + 3x - 1
f(x) - g(x) = 2x^2 + 5x - 2

a: -3n+1
b:-5n-2
Step-by-step explanation:
a: it is -3+1 because you can see that the sequence is going down by 3, so it is the 3 times table, but because the number is 4, and 4 is 1 more than 3, you put plus one at the end. :)
