Exponential function
As a last topic in this section we have to discuss a special exponential function. Actually this is so special that for several people it is THE exponential function. Following it is,
f( x ) = ex
where e = 2.718281828...... . Note the difference among f( x )= b x and f( x ) = ex . In the primary case b is any number which is meets the limitation given above whereas e is a very specific number. Also note that e is not a terminating decimal.
This special exponential function is extremely important & arises obviously in several areas. As noted above, this function arises so frequently that several people will think of this function if you talk regarding exponential functions. Let's get a quick graph of this function.
A college student invested part of a $25,000 inheritance at 7% interest and the rest at 6%. If his annual interest is $1,670 how much did he invest at 6%? If I told you the answe

A police academy is training 14 new recruits. Some are working dogs and others are police officers. There are 38 legs in all. How many of each type of recruits are there?
Definition of an exponential function If b is any number like that b = 0 and b ≠ 1 then an exponential function is function in the form,
A=8 AND R=2 THEN WHAT IS A+R-10
The sum of 2 numbers is 37.If the large is divided by the smaller,the quotient is 3 and the remainder is 5.Find the numbers
f(x)=-12x^2-24x+7

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
