Domain and Range
The domain of any equation is the set of all x's which we can plug in the equation & get back a real number for y. The range of any equation is the set of all y's which we can ever get out of the equation.
Note that we did mean to employ equation in the definitions above rather than functions. These are actually definitions for equations. Though, as functions are also equations we can employ the definitions for functions as well.
Finding the range of an equation/function can be pretty hard to do for various functions and thus we aren't going to actually get into that. Here we are much more interested in finding the domains of functions. From definition the domain is the set of all x's which we can plug in a function & get back a real number. At this instance, that means that we have to ignore division by zero and taking square roots of negative numbers.
Suppose an economy has four sectors, Agriculture (A), Energy (E), Manufacturing (M), and Transportation (T). Sector A sells 10% of its output to E and 25% to M and retains the rest
When is a problem an empty set and when do you have to solve for two problems when doing an equation?
Multiply a Row by a Constant. In this operation we multiply row i by a constant c and the notation will utilizes here is cR i . Note that we can also divide a row by a constant
The luck dragon that live in the enchanted Forest weigh 4x pounds when they are x years old. Write a function table that can be used to find the weights of 6-year old, 8-year old,
Now we need to discuss graphing functions. If we recall from the earlier section we said that f ( x ) is nothing more than a fancy way of writing y. It means that already we kno
let x,y,z be the complex number such that x+y+z=2,x^2+y^2+z^=3,x*y*z=4,then 1/(x*y+z-1)+1/(x*z+y-1)+1/(y*z+x-1) is
x^2+2x
