Which divisor of -2x^3 - 5x^2 + 4x - 2 results in a remainder of -14

Vsevolod [243]

Answer:

$f(x) = -2x^3 -5x^2 +4x -2\\option 1 : x+2 \\f(-2) = -2(-2)^3 -5(-2)^2 +4(-2)-2 = 16 -20-8-2= -14\\\\\\option 2: x+3\\f(-3) = -2(-3)^3 -5(-3)^2 +4(-3) - 2 = 54 -45 -12-2 = -5\\\\option 3: x-2\\f(2) = -2(2)^3-5(2)^2-4(2)-2=-16 -20-8-2=-46\\\\option4 :x-3\\f(3) = -2(3)^3 - 5(3)^2-4(3)-2 = -54-45-12-2=-113\\$

option 1: x + 2

The function f(x)={1/5}^x is translated up 4 units. Which equation represents the translated function

insens350 [35]

$f(x+n)\to\text{translation n units left}\\\\f(x-n)\to\text{translation n units right}\\\\f(x)+n\to\text{translation n units up}\\\\f(x)-n\to\text{translation n units down}\\\\\\f(x)=\left(\dfrac{1}{5}\right)^x\to f(x)+4=\left(\dfrac{1}{5}\right)^x+4\\\\Answer:\ g(x)=\left(\dfrac{1}{5}\right)^x+4$

I’ll mark you brainlist SHOW WORK WRITE IN y=mx+b form

Dovator [93]

Step-by-step explanation:

find slope first

38-8/-14-(-20) = 5

y = 5x + b

find y intercept by sub in any set value show as long as they are belongs together

8 = 5(-20) + b

8 = -100 + b

108 = b

y = 5x + 108
