Keesha was asked to use the remainder theorem to determine whether x+1 is a factor of the function f(x)=x^3+2x^2-5x-6 . which statement can be determined to be true using keesha's results?

a. 1 is a zero of the function because the remainder is zero.

b. 1 is a zero of the function because it is the coefficient of the first
term.

c. –1 is a zero of the function because the remainder is zero.

d. –1 is a zero of the function because it is a factor of the last term.

the answer is 15% decrease

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
