Step-by-step explanation:
Answer:
C
Step-by-step explanation:
x^3+4x^2-9x-36=0
or x²(x+4)-9(x+4)=0
or (x+4)(x²-9)=0
or (x+4)(x+3)(x-3)=0
x=-4,-3 or 3
Answer:
The polynomial of minimum degree is
.
Step-by-step explanation:
According to the statement, we appreciate that polynomial pass through the following points:
(i)
, (ii)
, (iii)
, (iv) 
From Algebra we know that any n-th grade polynomial can be constructed by knowing n+1 different points. Hence, the polynomial of minimum degree is a quartic function. The polynomial has the following form:

We proceed to expand the expression until standard form is obtained:




If we know that
, then:



Then, the polynomial is:



The polynomial of minimum degree is
.
2.7 is 27/10 and 3.6 is 18/5
