Ulleksa [173]

$\longrightarrow (-\dfrac{1}{2} +2)$

$\longrightarrow (-\dfrac{1}{2} +\dfrac{4}{2} )$

$\longrightarrow \dfrac{-1+4}{2}$

$\longrightarrow \dfrac{3}{2}$

$\sf \bold{\longrightarrow 1\dfrac{1}{2}}$ (final answer)

$\longrightarrow \sf 4(\dfrac{1}{2} +\dfrac{5}{4} ) + (-5)$

$\longrightarrow \sf 4(\dfrac{2}{4} +\dfrac{5}{4} ) + (-5)$

$\longrightarrow \sf 4(\dfrac{7}{4} ) + (-5)$

$\longrightarrow \sf 7-5$

$\longrightarrow \bold{\sf 2}$ (final answer)

What is the interval of increase and decrease of f(x)= (x-4)^2 -1

nevsk [136]

Answer:

(−∞,4)

Step-by-step explanation:

Explanation:

To determine the interval that f(x) is increasing.

increasing when f'(x)>0f'(x)=−2(x−4)← using chain rule

solve −2(x−4)>0

⇒−2x+8>0

⇒x<4

interval is (−∞,4)

graph{-(x-4)^2-3 [-8.89, 8.89, -4.445, 4.44]}
