Inverse Functions (48 problems) - Group Activity (competition)

This is a collaborative group activity (for groups of 2, 3 and/or 4 members) on inverse functions. It consists of 12 sections as in each section there are 4 similar problems – one problem for each of the partners.

The functions included are linear (in section 1);quadratic functon in standard form (section 2) ;quadratic functions in vertex form (section 3);cubic functions in the form (x+a)^3 + b (section 4);polynomial functions in the form a(x+b)^n+c (section 5); square root functions in the form a + b√(x+c) (section 6);cube root functions c + ∛(ax+b) (section 7);n-root functions (section 8);rational functions of the type (ax+b)/(cx+d) (section 9);exponential functions of the type e^(ax+b) + c (section 10); logarithmic functions ln(ax+b) (section 11); trigonometric functions of the type asin(x+b), acos(x+b), atan(x+b) and acot(x+b) (section 12)

This activity may be turned into a competition between groups. In each section, it is given the certain number of points that each problem solved correctly gives. The number of points are directly proportional to the difficulty level of the problems.

Students recording sheets are provided. Answer keys are included.
