Answer:
Step-by-step explanation:
Given that the exponential function passes through the point (2,80)
Since only one point is given there may be more than one exponential function satisfying this.
One of them we select here is with base 4 and coefficient 5.
i.e.
We can check whether (2,80) lies on it.
Substitute x=2 and y =80
Left side =80
Right side =

Answer:
Step-by-step explanation:
Let say; By y(x)= y(e)
we have;
Using Fundamental Theorem of Calculus and differentiating by Lebiniz Rule:
dy/dx = 1/xy
RECALL: y(e) = 3
MULTIPLYING BOTH SIDE BY 2 , TO ELIMINATE THE DENOMINATOR, WE HAVE;
