You posted this in the basic algebra forum.
Therefore, I think that you are meant to graph the expression.
See where the zeros would be and then ‘zoom in’ on them.
It appears that it has two roots between 0 & 5.
Came across an exponential equation that I am having a hard time solving. If anyone can walk me through this it would be appreciated...
Problem says use the calculator to obtain a decimal approximation for the solution.
Thanks in advance.
maybe I posted in the wrong section. I believe I have to somehow use log or ln in this problem, as that is the chapter we are currently on. If it had just been 2^x + 1 i could do. But that -4x throws me off.
The multiple choice answers are A. .639, 3.847 B. .639 C. 14.387 D. 3.847
The function is continuous on . Besides , , and . According to Bolzano's Theorem there are two solutions and for the equation . It is easy to prove that the equation has not more solutions.
Now using the calculator, you can try etc.
