Derivative Property [Multiplied Constant]:                                                           [tex]\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)[/tex]

Derivative Property [Addition/Subtraction]:                                                         [tex]\displaystyle \frac{d}{dx}[f(x) + g(x)] = \frac{d}{dx}[f(x)] + \frac{d}{dx}[g(x)][/tex]

Basic Power Rule:

  1. f(x) = cxⁿ
  2. f’(x) = c·nxⁿ⁻¹  

Step-by-step explanation:

Step 1: Define

Identify

[tex]\displaystyle f(x) = 8x + 7[/tex]

Step 2: Differentiate

  1. Derivative Property [Addition/Subtraction]:                                                 [tex]\displaystyle f'(x) = \frac{d}{dx}[8x] + \frac{d}{dx}[7][/tex]
  2. Rewrite [Derivative Property - Multiplied Constant]:                                   [tex]\displaystyle f'(x) = 8\frac{d}{dx}[x] + \frac{d}{dx}[7][/tex]
  3. Basic Power Rule:                                                                                         [tex]\displaystyle f'(x) = 8[/tex]
