Assignment:
For the exponential function ex and logarithmic function log x, graphically show the effect if x is halved. Include a table of values for all four functions.
Evaluate the functions for the values of x given as 1, 2, 4, 8, and 16. Rank in order from fastest to slowest the rate at which each function changes with increasing values of x.
1. f(x) = 2x - 5
2. f(x) = x^2 - 4x + 3
3. f(x) = x^3 + 4x^2 - 2x - 3
4. f(x) = 7x
5. f(x) = log x
Provide complete and step by step solution for the question and show calculations and use formulas.
