3. For this problem, we define the function g(x) = 2³+x-1. We want to
find a number x such that g(x) = 0. In other words, we want to solve the
equation ³+x-1=0. You may use a calculator for this question.
(a) Calculate g(0) and g(1). This guarantees there has to be some number
0 < x < 1 such that g(x) = 0. Why? Hint: which theorem we can imply here.
We are going to make a bunch of successive guesses for the solution to
the equation. None of them will be exact, but each one will be better than the
previous one. Our first guess is going to be z₁ = 1. Write the equation of the
line tangent to y = g(x) at the point with x-coordinate 21. Draw this line. We
will call it L1.
