Determine the roots of f(x) = -12-2.1x+18x^2-2.75x^3 graphically. in addition, determine the first root of the function with

The given function is that is a cubic polynomial

when arranged in descending order that is from highest degree to lowest degree

Since it is a three degree polynomial it has three roots.

According to rational root theorem , the possible roots of the above expression that is factors of  =  are

As you can see from the graph all roots of this polynomial are real.

The smallest positive root is 0.954 and smallest negative root are -0.724.

answer:

c. the third graph

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
