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.
Example If 8 ×10 14 joules of energy is released at the time of an earthquake what was the magnitude of the earthquake? Solution There actually isn't much to do here o
Find out the domain of each of the following functions. g( x ) = x+3 /x 2 + 3x -10 Solution The domain for this function is all of the values of x for which we don't hav
In previous section we looked at the two functions f ( x) = 3x - 2 and g ( x )= x/3 + 2/3 and saw that ( f o g ) ( x ) =(g o f )( x ) =
We now can also combine the two shifts we only got done looking at into single problem. If we know the graph of f ( x ) the graph of g ( x ) = f ( x + c ) + k will be the graph of
brody rode his bike 70 miles in 4 hours. he rode at an average speed of 17 mph for t hours and at an average rate of speed of 22 mph for the rest of the time. how long did brody ri
In this section we will discussed about non-linear systems of equations. A non-linear system of equations is a system wherein at least one of the variables contains an exponent ot
In the earlier section we looked at using factoring & the square root property to solve out quadratic equations. The problem is that both of these methods will not always work. Not
