Which of the following is an x-intercept of the function, f(x)=x^3-x^2-8x+12?

a. 4
b.-3
c.3
d.-4

Option B.-3

Step-by-step explanation:

we know that

An x-intercept is a value of x when the value of the function f(x) is equal to zero

we have

Determine the roots of the function f(x) by graphing

using a graphing tool

The roots are x=-3, x=2

see the attached figure

correct answer:

i^31 = -i

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
