Help please need this answer

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
