Locating Zeros of Polynomial Function:<br>Approximate the real zeros to the nearest tenth
solmaris [256]

we are given

f(x)=2x^4-x^3+x-2

we can check each options

option-A:

-1,1

we can plug x=-1 and x=1 and check whethet f(x)=0

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

At x=1:

f(1)=2(1)^4-(1)^3+(1)-2

f(1)=0

so, this is TRUE

option-B:

0,1

we can plug x=0 and x=1 and check whethet f(x)=0

At x=0:

f(0)=2(0)^4-(0)^3+(0)-2

f(0)=-2

At x=1:

f(1)=2(1)^4-(1)^3+(1)-2

f(1)=0

so, this is FALSE

option-C:

-2,-1

we can plug x=-2 and x=-1 and check whethet f(x)=0

At x=-2:

f(-2)=2(-2)^4-(-2)^3+(-2)-2

f(-2)=36

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

so, this is FALSE

option-D:

-1,0

we can plug x=-1 and x=0 and check whethet f(x)=0

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

At x=0:

f(0)=2(0)^4-(0)^3+(0)-2

f(0)=-2

so, this is FALSE
