**Question 1. Question: (TCO 2)** Find y’:

y = log2(4×3)

**Question 2. Question : (TCO 2)** Expand using the rules of logarithms, then differentiate:

y = ln(3) + ln(x) – ln(3x) – ln(7),

y = ln(3) + ln(x) – ln(3x) – ln(7),

y = ln(3x) – ln(3x + 7),

y = ln(3) + ln(x) – ln(3x + 7),

**Question 3. Question : (TCO 2)**** **Find y’:

**Question 4. Question : (TCO 2)** ) Find y’ and y’’:
