General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -3 does indeed equal -3.

∴ x = -1 is a solution of the equation.

(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
