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 ...

You have titled the post "algebra 2". Does that mean that you have done calculus, or should the solution be without calculus? We usually solve maximization problems by linear programming or calculus. However, this problem can also be solved by tabulation without using calculus...

that would be dy/dx = -8x - 17 I am somewhat bothered by your question. If you are studying Calculus, then you should have known the answer. If you are not taking Calculus, then the question does not belong. The type of problem you asked is fundamental to the study of Calculus.

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) =A((x + (B...

**Calculus**

If you have done functions before calculus as most students do, you can rewrite the equation in the standard form: f(x)=a(x-h)+k where the vertex is found at (h,k) or f(x)=-(3/4)(x-2)²+3 where the vertex is found at (2,3). Confirm by Calculus: f(x)=3x-3/4x^2 f'(x)=3-(3/2)...
