The temps that we know are colder than -5deg C 

first anything below or less than -5degC will be colder in temperature because it has a lower or smaller value, so it is colder overall. 

3 examples would be x<-5deg C

x= -6deg C
x= -7deg C
x= -8deg C

so plugging in x value we get -6<-5   -7<-5    -8<-5

If you are needing anything else please just ask! Thank you!

Find a polynomial f(x) of degree 4 that has the following zeros.<br> 0, -5, 8, -2
Roman55 [17]

Answer:

The polynomial of the function degree '4'

x⁴ - x³ -46 x² -80x =0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given zeros are 0 ,-5,8,-2

x =0 , x=-5 ,x=8 and x=-2

(x-0) , ( x+5) , (x-8) and (x+2)

The polynomial function with degree '4'

(x-0)(x-(-5)(x-8)(x-(-2) =0

x ( x+5) (x-8) (x+2) =0

(x² +5x)(x-8)(x+2) =0

(x³ -8 x²+5x² -40 x)(x+2) =0

( x³ -3 x² - 40 x) (x +2) =0

x⁴ + 2 x³ - 3 x³- 6 x²-40 x²- 80 x =0

x⁴ - x³ -46 x² -80x =0

<u><em>Final answer:-</em></u>

The polynomial of the function degree '4'

x⁴ - x³ -46 x² -80x =0
