Ok, these are problems from a summer packet I have to turn in for precalc honors. The problems are based around algebra 2.
Find the inverses, f^-1(x) of the following functions using 3 different methods.
f(x)=x^2 +2x -5
f(x)=log_9e^sin(x/2) <---I really need help with this one.
Solve each of the following systems algebraically and using matrices
√3x - 2y = -1
2x + 5y^2 = 12
