Graphs and Functions

Word problem

George has decided that a distribution of data is cubic, that is it has the general form of a function "f(x)=x^3" if the point on the curve that should be at (0,0) is found at (-3,7) and the point that should be at (1,1) is at (-2,11). What is the equation of the data distribution (hint: sketch f(x)=x^3 and the points (-3,7) and

Graph equation

Plot f(x)=3(x-7)^2+5 using transformations. Track the points (0,0)(1,1) and (-1,1) from the reference equation (graph) to their final position.

Objective functions with constraints

An objective function is to be maximized given the following constraints: x+2y=4, x-y=1, x=0, y=0. Find the vertices of the set of feasible solutions.

Question about One-to-one functions

Define F: power P({a, b, c}) -> Z as follows: for all A exist in power P({a, b, c}), F(A) = the number of elements in A. a). Is F one-to-one? Please give proof or give a counterexample. Please explain so I may understand. Thanks

Maximal, greatest, minimal, least elements

Given S = {0, 1}, let R be the partial order relation on S X S X S such that for all ordered triples (a, b, c) and (d, e, f) in SXSXS (a, b, c) is related to (d, e, f) &#61659; a =<d, b=<e, c=<f, where =< denotes the usual "less than or equal to" relation for real numbers. Give all maximal, greatest, minimal and least elements
