Ответ:
There does not exist any solution of
as thir graphs do not intersect.
Step-by-step explanation:
We are given that,
The values of the exponential function f(x) are f(1)= 2 and f(2)= 6.
That is, we get,
So, the function f(x) is
.
Moreover, the values of the linear function g(x) are g(1) = 2.5 and g(2) = 4.
That is, the slope =
= 1.5
Substituting the slope and point (1,2.5) in the linear equation
, where m is the slope, we get,
i.e. b= 1
Thus, the function g(x) is
.
Consider,![f(x)=g(x)](/tpl/images/0443/1555/b2e82.png)
i.e.![2(3)^x=2.5x+1](/tpl/images/0443/1555/ecbd4.png)
Now, the function f(x) is exponentially increasing and the linear function g(x) is increasing between x= 1 and x= 2, but there is no point where the graphs of the functions are intersecting.
Thus, there is no solution of the equation
