Step 1
1. Plot the function \( f(x) = -25 + 82x - 90x^2 + 44x^3 - 8x^4 + 0.7x^5 \) over a reasonable range of \( x \) values, such as from \( x = 0 \) to \( x = 2 \). 1.2. Identify the point where the curve crosses the x-axis. This point is the real root of the function. Show more…

Determine the real root of the equation f(x)= ln(x - 2) - 1 until you reach an approximate error of less than 10%. Use initial estimates of xl = 3.0 and xu = 6.0. It must be done by: a) Bisection Method b) False position c) Evaluate the results by comparing both methods.
