Answer:

Step-by-step explanation:

g(-2)=2(-2)^3+3(-2)^2-3(-2)+4=-16+12+6+4=6

g(-1)=2(-1)^3+3(-1)^2-3(-1)+4=-2+3+3+4=8

it does not change sign ,so there is no real zero between -2 and -1.

Answer:

mATHeMaTics is Very FUN

Step-by-step explanation:

When coding the word OUCH using the Bacon's code alphabet with binary numbers we have:

O=01110

U=10100

C=00010

H=00111

Following the rule of lowercase and uppercase letters in the dummy message we will have:

O U C H
