1) Graph these functions using a graphing calculator or program: f(x) = x^2 + 5 g(x) = 2x + 5 h(x)= x^3 + 5 What similarities and differences can you see among them? 2) Given the above functions, do you think that all linear equations can be expressed as functions?

**Math - Domain of Composite**

You do not state what composite function you want. Do you want f(g(x)) or g(f(x)) or f(x)*g(x) ..... Does the following reply answer your question? http://www.jiskha.com/display.cgi?id=1307080009

Do you know what the parent functions of y = sqrt(x) and y = x^3 look like? The functions f and g are simply those parent functions with a horizontal shift.

Tony and Tom are brothers.This year both of their ages are prime numbers. Last year both of their ages were composite numbers. Both of their ages will be composite numbers again over the next three years. If Tony and Tom are both teenagers, how old are they now?

Is it possible to graph linear functions like h(x) = 3x + 7 without doing a table of values? If it is, how? And I know the slope is 7, which means the y-intercept is (0,7).

**Composite Functions**

f(g) = (7g+28)/(g-3) = (7(3x+28)/(x-7) + 28)/(3x+28)/(x-7) - 3) = x g(f) = (3f+28)/(f-7) = (3(7x+28)/(x-3) + 28) / ((7x+28)/(x-3) - 7) = x How odd! However, if you solve for f-1(x) you get g(x) and vice-versa. f(g(-1)) = f(-1) = -1
