I am too embarassed to ask this Calculus (really pre-calculus) question in tutoring, because I know I should know. Is the inverse of f(x)=3x-1 actually f(x)=1/3x+1? How do I find it? What if it asks the same equation replaced with f to the -1 power (x)? I think I know how the ...

Are you doing pre-calculus or calculus? In calculus, the maximum is obtained by setting f'(t)=derivative with respect to t = 0 and solving for t. In pre-calculus, you can transform the expression by completing the squares. Ax² + Bx + C =A(x²+ (B/A)x + C/A...

Pre-Calculus? That is a nasty equation. We might use Newton's Method, but that would be Calculus. I tried some "trial and erro" and got x = appr .371 using 2 decimals 4 sin .37 = 1.44646 e^.37 = 1.4477 I am curious what method was suggested that you should use.

Pre calculus? This is stock Algebra II. put the equations in the form of ax^2+bx+c=0 then factor. for instance, c is already in that form. 2x^2+x-6=0 (2x-3)(x+2)=0 x= 3/2 x=-2 do the others the same method.

The "dx" at the end makes me think you are supposed to integrate [e^-x / e^-1] + 3 . But that would make it a calculus, not a precalculus, question. It is not clear what the question is. In any case, e^-x / e^-1 = e^(1-x) The integral of e^(1-x) + 3 dx is -e^(1-x) + ...
