Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{(x + 4) and (x - 1)}}}}}$

Step-by-step explanation:

$\sf{ {x}^{2} + 3x - 4}$

Find the two numbers that multiplies to 4 and subtracts to 3. The numbers are 4 and 1

$\dashrightarrow{ \sf{ {x}^{2} + (4 - 1)x - 4}}$

$\dashrightarrow{ \sf{ {x}^{2} + 4x - x - 4}}$

Take x as common

$\dashrightarrow{ \sf{x(x + 4) -x - 4}}$

Take 1 as common

$\dashrightarrow{ \sf{x(x + 4) - 1(x + 4)}}$

$\dashrightarrow{ \sf{(x + 4)(x - 1)}}$

Hope I helped!

Best regards! :D

Find the absolute maximum and absolute minimum values, if any, of the function. (If an answer does not exist, enter DNE.)f(x) =

lyudmila [28]

Answer:

The absolute minimum value is " $-\frac{21}{4}$ " and the absolute maximum value is " $15$ ".

Step-by-step explanation:

Given:

$f(x)=x^2-x-5$

on,

$[0,5]$

By differentiating it, we get

⇒ $f'(x)=2x-1$

Set $f'(x)=0$

then,

⇒ $2x-1=0$

$2x=1$

$x=\frac{1}{2}$ (Critical point)

When x=0,

⇒ $f(x)=-5$

When $x=\frac{1}{2}$ ,

⇒ $f(x)=-\frac{21}{4}$ (Absolute minimum)

When $x=5$

⇒ $f(x)=15$ (Absolute maximum)
