I have to do a lot of homework problems like this but I do not really understand how to do any of them. Can someone show me how to do this one so I can do the rest of my homework problems on my own? Thanks.
Let A = (a, f(a)) and B = (b, f(b))
Write an equation for:
a) the secant line AB
b) a tangent line to f in the interval (a,b) that is parallel to AB
1. f(x) = x + 1/x, interval: x is less than or equal to 2 but greater than or equal to 0.5
