QUESTION 1

Let f be a function defined by

f(x)=(x^2)/((-2 x+1)^2)

(a) Use the sign pattern for f^'(x) to determine
(i) the interval(s) over which f rises and where it falls;
(ii) the coordinates of the local extreme point(s).

Step 1

The quotient rule states that if \( f(x) = \frac{u(x)}{v(x)} \), then \[ f'(x) = \frac{u'(x)v(x) - u(x)v'(x)}{(v(x))^2} \] For \( f(x) = \frac{x^2}{(-2x+1)^2} \), let \( u(x) = x^2 \) and \( v(x) = (-2x+1)^2 \). Show more…
