Answer:

4

Step-by-step explanation:

$p(x) = (x - 1) (x + 1) \\ plug \: x = 2 \: 1 \: 0 \: we \: find: \\ \\ p(2) = (2 - 1) (2 + 1) = (1)(3) = 3 \\ p(1) = (1 - 1) (1 + 1) = (0)(2) = 0 \\ p(0) = (0 - 1) (0 + 1) = ( - 1)(1) = - 1 \\ \\ p(2) + p(1) - p(0) \\ = 3 + 0 - ( - 1) \\ = 3 + 1 \\ = 4$

Hi, Could anyone help me with my homework

Answer:

$\hookrightarrow \sf x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096$

solving steps:

$\rightarrow \sf (x + 4)^6$

$\bold{rewrite \ the \ following}$

$\rightarrow \sf (x + 4)^2 (x + 4)^2 (x + 4)^2$

$\bold {formula \ used : \sf (x+a)^2 = (x^2 + 2xa + a^2)}$

$\rightarrow \sf (x^2 + 8x+16) (x^2 + 8x+16) (x^2 + 8x+16)$

$\bold{simplify \ by \ removing \ parenthesis}$

$\rightarrow \sf (x^4 +8x^3 + 16x^2 + 8x^3 +64x^2 + 128x+16x^2+128x+256 ) (x^2 + 8x+16)$

$\bold{basic \ addition \ of \ integers }$

$\rightarrow \sf (x^4+16x^3+96x^2+256x+256) (x^2 + 8x+16)$

$\bold{remove \ parenthesis}$

$\rightarrow \sf (x^6 + 16x^5 + 96x^4 + 256x^3 + 256x^2 + 8x^6 + 128x^4 + 768x^3 + 2048x^2 + 2048 + 16x^4 + 256x^3 + 1536x^2 + 4096x + 4096)$

$\bold {final \ answer:}$

$\rightarrow \sf x^6+24x^5+240x^4+1280x^3+3840x^2+6144x+4096$

HEY GUYS THIS IS MY FINAL MATH ASSIGNMENT OF THE YEAR... PLS JUST HELP ME FIND THE DOMAIN AND RANGE THANK YOU

Gnom [1K]

Answer:

domain: all real numbers (-∞,∞)

range: y ≤ 64

Step-by-step explanation:

since the domain is arn,

and range is the coordinates

coordniate (top or bottom-most point)

downward facing so the top

(2, 64)

since it is downward facing we use ≤ instead of ≥

y value is 64 (just as x is 2)

your answer is y ≤ 64

hope this helps:)

The function rule C = 40n + 210 relates the number of months n to cost in dollars C of a phone plan and budget phone. Make a tab

Viefleur [7K]

Answer:

Input - Output

2 - $290

12 - $690

24 - $1170

Step-by-step explanation:

Cost after n months:

The cost after n months is given by the following function:

$C(n) = 40n + 210$

After 2 months:

This is C(2). So

$C(2) = 40(2) + 210 = 80 + 210 = 290$

After 12 months:

This is C(12). So

$C(12) = 40(12) + 210 = 480 + 210 = 690$

After 24 months:

This is C(24). So

$C(24) = 40(24) + 210 = 960 + 210 = 1170$

Table:

Input - Output

2 - $290

12 - $690

24 - $1170
