91.
given f(x)=ln(x)
f(0)=ln(0)=

so, F

92. correct
93. correct
94. correct
95. correct ...........................if f(u)=2(f(v)=> ln(u)=2(ln(v)) , since 2(ln(v))=ln(v^2) we have ln(u)=ln(v^2)=> should be u=v^2
96. correct

More questions later on my meal break at the job. Tonight is my Friday. Thank God! This weekend, I plan to purchase an acoustic guitar at Guitar Center. I have been playing guitar since 1977. I used to play at a Brooklyn home Bible study group and at the Ebenezer Church (also in Brooklyn) back in the 1980s. I read and write basic guitar tablature. More later....

Do you still play guitar and mandolin? It's just something to do. I enjoy writing my own music. I play hymns in the fingerstyle method. Hymns are my favorite, especially on the classical guitar.

This is my style of playing. Enjoy I Surrender All.
