The expression without using absolute value is 2z - 11

<h3>Absolute value of a function</h3>

Given the expression with absolute value expressed as:

lz-6l-lz-5l

Since absolute function can both be negative or positive, hence;

lz-6l-lz-5l = z - 6 - -(z - 5)

lz-6l-lz-5l = z-6-(-z+5)

lz-6l-lz-5l = z - 6 + z - 5

lz-6l-lz-5l = 2z - 11

Hence the expression without using absolute value is 2z - 11

Y = 3x +1; domain = {-1, 0, 1}<br> HELP PLEASE

ser-zykov [4K]

We have to put values of domain to find range

$\\ \ast\sf\longmapsto y=3x+1$

$\\ \ast\sf\longmapsto D_R=[-1,0,1]$

$\\ \ast\sf\longmapsto y=3(-1)+1=-3+1=-2$

$\\ \ast\sf\longmapsto y=3(0)+1=0+1=1$

$\\ \ast\sf\longmapsto y=3(4)+1=12+1=13$

Now

$\\ \ast\sf\longmapsto R_R=[-2,1,13]$

Evaluate the function for the given value.<br> If f(x) = -3x2 – 8, then f(-4)= ?

Ganezh [65]

Answer:

The answer is

Step-by-step explanation:

$f(x) = - 3 {x}^{2} - 8 \\$

To find f(-4) , substitute the value of x that's - 4 into f(x). That is for every x in f(x) , replace it with - 4

We have

$f( - 4) = - 3 ({ - 4})^{2} - 8 \\ = - 3(16) - 8 \\ = - 48 - 8 \: \: \: \: \:$

We have the final answer as

$f( - 4) = - 56$

Hope this helps you

Factor<br> With detail please<br> (X+1)^2-4

lesantik [10]

First simplify
(x^2+2x+1)-4
x^2+2x-3
Then factor
(x+3)(x-1)=x^2+2x-3
I solved your other quesiton too.
