Step-by-step explanation:
The number that is being multiplied by the variable ( the letter) so like if you have 2X the 2 is the coefficient
Answer:
-13/20
Step-by-step explanation:
-4/5 x 4/4 = -16/20
3/20 x 1/1 = 3/20
-16/20 + 3/20 = (-16 + 3 = -13)
-13/20
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.
Answer:
the answer is c
