Find and simplify each of the following for \( f(x)=6 x^{2}-7 x+6 \) (A) \( f(x+h) \) (B) \( f(x+h)-f(x) \) (C) \( \frac{f(x+h)-f(x)}{h} \)

Exercise \#2. Calculate confidence intervals for the population mean when you do not know the population standard deviation. Use the following information to complete the calculations. Show your work. Formula: \( \bar{x} \pm t\left(\frac{s}{\sqrt{n}}\right) \) (2a) Assume the following: \( \bar{x}=60 \mathrm{~s}=7 \quad n=81 \) Calculate confidence intervals for a \( 95 \% \) confidence level. Calculate confidence intervals for a 99\% confidence level.

2. \( 27^{1-x}=\frac{1}{81} \)
