1. find a formula for f^-1(x) given f(x)=ln(2x-5)
2.given f(x)=x^3-4x^2-11x+30 (a)find the zeros and (b) write a linear factorization of the function.
3.You are planning to make an open rectangular box from a 20 by 25in piece of cardboard by cutting congruent squares of side x from the corners and folding up the sides.
(a) write a funtion V(x)for the volume of the box
(b)what is the domain of V?
(c) Graph the function on your calculator and find the maximum volume
(d) what are the dimmensions of the box yielding the maximum volume?
4. Solve algebraically. what is the significance of the solution in terms of the graph of the two equations?
3x-5y=12
6x-10y=14
i will +rep a minimum of one point per answered correct question. different parts (a, b, c, ect all count as there own question.)
also if you answer them all, i will +10 rep you as soon as i can!
