Find the equation of the line tangent to the graph of f at

Question

Q1. Find the equation of the line tangent to the graph of f at the indicated value of x.

f(x) = 5 - 2 lnx; x = 1

Q2. Find f'(x).

f(x) = (x² - 2)(x² + 6)

Q3. Solve for t to two decimal places.

7 = e^0.08t

Q4. Find use the appropriate properties of logarithms to rewrite f(x), and then find f'(x).

f(x) = 24x + ln 24x

Q5. Use the quotient rule to find the derivative of the following.

y = (8x²+5/x²+2)
