Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a star
n200080 [17]

Answer:

<em>x=25/16</em>

Step-by-step explanation:

<u>Approximate Roots of Functions:</u>

We are required to find the root of  

\displaystyle 5^{-x}+7=\ 2x+4

Let's construct a function

\displaystyle f(x)=\ 5^{-x}+7-2x-4

Reducing:

\displaystyle f(x)= 5^{-x}-2x+3

The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)

\displaystyle f(1.5)=5^{-1.5}-2(1.5)+3\ =0.089

We'll move up on x=1.52  

\displaystyle f(1.52)=5^{-1.52}-2(1.52)+3=\ 0.046

We are closer to the solution, let's try some more up

\displaystyle f(1.54)=5^{-1.54}-2(1.54)+3=\ 0.0038

This value x=1.54 is close enough to the solution of the original equation

From the options given, \frac{25}{16} is the closest to our solution

\boxed{Answer:\ x=25/16}
