This is all I have time for right now.Have a few questions that have to deal with logarithims. I dont quite understand them all and need some help. The first question is
1. Use what you know about polynomials to find the maximum value of the function. F(x)= 3+4x^2 - x^4 (Hint: set t=x^2)
Mr F says: The maximum value of F(x) is the same as the maximum value of G(t) = 3 + 4t - t^2. Do you know how to find the maximum value of a parabola?
5. Find the following;
a. f(x) = ln(ln(ln x)
b. f(x) = log base 2(log base 10(x))
Mr F says: What are you meant to find ....?
6. Use the change of base formula to show that
a. Log base 10 = (1/ln 10) Mr F says: Log base 10 of what ....? Either the argument of the log is missing or the base is missing ....
