Question 542546
I need help on how to solve this and how to solve this with a calculator. Can someone please help me?
2.0e^(-1.5x)=1
---
Calculator:
Graph 
Y1 = 2*e^(-1.5x)
Y2 = 1
----
Graph them on the same set of axes and find their point of intersection.
{{{graph(400,400,-10,10,-3,3,2e^(-1.5x),1)}}}
----
Algebraic:
e^(-1.5x) = 1/2
Take the natural log of both sides to get:
-1.5x = ln(1/2)
x = 0.4621
