critical f(x)=sin^2(7x)

critical points

f (x) = sin^{2} (7 x)

x = \frac{π}{7} n, x = \frac{π}{14} + \frac{π}{7} n

Solution steps

sin^{2} (7 x)

Find where

f^{'} (x)

is equal to zero or undefined

x = \frac{π}{7} n, x = \frac{π}{14} + \frac{π}{7} n

Identify critical points not in

f (x)

domain

Domain of

sin^{2} (7 x) : - \infty < x < \infty

All critical points are in domain

x = \frac{π}{7} n, x = \frac{π}{14} + \frac{π}{7} n

(3 x - 7)^{3}

5 lo g_{4} (x)

f (x) = \frac{x ^{3}}{x ^{2} - 4}

f (x) = \frac{3}{x}

f (x) = ln (t + 4)
