  1. Derivative of linear term 12x12x12x is the coefficient.

Flashcard 6: What is the derivative of a constant multiplied by xxx, 7x7x7x?

Answer:

  1. Constant multiple rule: derivative of cxcxcx is ccc.

Flashcard 7: Find the derivative of 8x−28x - 28x−2.

Answer:

  1. Derivative of linear term is its coefficient.

Flashcard 8: State the derivative of xnx^nxn where nnn is a constant.

Answer: nxn−1nx^{n-1}nxn−1. Power rule: bring down exponent, reduce by 1.

Answer: 2x + 3. Apply power rule to each term separately.

Flashcard 10: What is the derivative of cf(x)cf(x)cf(x), where ccc is a constant?

Answer: (cf)′=cf′(cf)' = cf'(cf)′=cf′. Constant multiple rule: factor out the constant.

Flashcard 11: State the derivative rule for the difference of two functions f(x)f(x)f(x) and g(x)g(x)g(x).

Answer: (f−g)′=f′−g′(f - g)' = f' - g'(f−g)′=f′−g′. Derivative of difference equals difference of derivatives.

Flashcard 14: State the derivative rule for the sum of two functions f(x)f(x)f(x) and g(x)g(x)g(x).

Answer: (f+g)′=f′+g′(f + g)' = f' + g'(f+g)′=f′+g′. Derivative of sum equals sum of derivatives.

Flashcard 15: Calculate the derivative of 7x3−4x7x^3 - 4x7x3−4x.

Answer: 21x^2 - 4. Use power rule: 7⋅3x2−4=21x2−47 \cdot 3x^2 - 4 = 21x^2 - 47⋅3x2−4=21x2−4.

Flashcard 16: Find the derivative of 8x−28x - 28x−2.

Answer:

  1. Derivative of linear term is its coefficient.

Flashcard 17: What is rac{d}{dx}[2f(x)+3g(x)-5]?

Answer: 2f′(x)+3g′(x)2f'(x)+3g'(x)2f′(x)+3g′(x). Constant -5 has derivative 0; apply rules to rest.

Flashcard 18: What is rac{d}{dx}[f(x)-g(x)+h(x)]?

Answer: f′(x)−g′(x)+h′(x)f'(x)-g'(x)+h'(x)f′(x)−g′(x)+h′(x). Apply sum/difference rules term by term.
