What is f(1.1)? What is f(1.2)? Are they of different sign? What does that tell you?the curve crosses the x-axis at points A and B
a. by calculation, show that the value of x at point A lies between 1.1 and 1.2
b. the value of x at the point B lies in the interval (n, n+1) where n is an integer. find n
for a. i took 12lnx = x^(3/2) and turned it all around, getting e^x^(3/2) = x^12 etc. but i still have no idea of how to get the interval for x
for b. i have no idea
For (b), Calculate f(n) for n= 2, 3, 4, 5,etc. until you find a root!
