critical 12x^2-72x+77

critical points

12 x^{2} - 72 x + 77

x = 3

Solution steps

12 x^{2} - 72 x + 77

Find where

f^{'} (x)

is equal to zero or undefined

x = 3

Identify critical points not in

f (x)

domain

Domain of

12 x^{2} - 72 x + 77 : - \infty < x < \infty

All critical points are in domain

x = 3

y = x^{2} - 8 x - 7

f (x) = sin^{2} (15 x)

f (x) = \frac{2 x}{x + 1}

f (x) = 15 + 5 x

\frac{2 x - 3}{x + 4}
