Question 445257
Solve the equation with a graphing calculator.Round to the nearest thousands. 
log2(x+3)=2x+1
Use change of base formula
----------------------
[log(x+3)/log(2)] = (2x+1)
------
Using your calculator:
Let the left side of the equation be Y1.
Let the right side of the equation be Y2
----
{{{graph(400,300,-5,10,-5,10,ln(x+3)/ln(2),2x+1)}}}
----
Find the intersection of the 2 graphs to find "x":
I get x = 0.378108
