Question

1. is the function f(x) = 6 / x is one-to-one. true or false

If ln a = 2.565 and ln b = 3.045, find ln(ab).4.

2. The value of the definite integral ?e?1??2xx2?xis 1. true or false

3. An equation for the tangent line to the graph of f(x)=ln(x2?1) at the point where x =2 is 4x?3y=?1.true or false

4. Using logarithmic differentiation, the derivative of y=x3??2x+3?(x?2)2is y?=x3??2x+3?(x?2)2[3x+12x+3?2x?2]. true or false

can you explain how to do it.  Arigat?

If ln a = 2.565 and ln b = 3.045, find ln(ab).

Explanation / Answer

1. True ln(ab) = lna + lnb = 2.565 + 3.045 = 5.710 4.) False 3.) False 2.)False
