Question

Use a graph calculator to approximate the solution of the equation round to the nearest thousandth

Answer 1

To answer this question using a graphing calculator, we can proceed as follows:

1. We can graph the function:

`f(x)=-((1)/(2))^(-x)`

2. Then we need to find, using the graph, the corresponding value for x for which y = -70.

Therefore, we have the graph of the function as follows:

And we can see that an approximate value for x, for which we have a value for y = -70 is, approximately:

Therefore, the value for the approximated solution for the equation is x = 6.129, if we round the value to the nearest thousandth.

We can check if this value is near
