AP Calculus Question

[From: ] [author: ] [Date: 11-08-27] [Hit: ]
:)-The easy solution turns out to be x = 1.The hard solution can be found by using a graphing calculator:x ≈ -1.Ordinarily, these types of equations cannot be solved algebraically because the left side is algebraic but the right side is transcendental.-There is no convenient inverse function to use to find x. However,......
All the question says is solve for x:
3 - x^2 = 2^x
(the 2 is an exponent of x and the x is an exponent of 2)
I wasn't sure if you would start by logging both sides of the equation? If you could show your process that would help me understand it better. Thanks in advance! :)

The easy solution turns out to be x = 1.

The hard solution can be found by using a graphing calculator: x ≈ -1.637

Ordinarily, these types of equations cannot be solved algebraically because the left side is algebraic but the right side is transcendental.

There is no convenient "inverse function" to use to find x. However, you can solve it by observation with a little bit of thought. Keep your ideas simple. Think simple number, and integer....

I hate to give it away. If you give yourself ONE minute, I'm sure you'll get it.

(BTW there is a second solution, but you'll need a calculator or computer to approximate it.)
