Question

slope of tanget line to to function y=1/√2x-1 at point a, using def'n of deriv; (b) at which point does tangent to function have slope of -1 and (c)find eq'n of tangent line at point in (b)? I got the deriv. wrong and have spent a long long time on this. please help...

Answer 1

Is this \[y=1/\sqrt{2x-1}\] or is it \[y=1/\sqrt{2}x-1\]

Answer 2

Hi there, it is the first question y=1/the square root of (2x-1) thanks!
