Which of these polynomial equations is of least degree and has -1, 2, and 4 as three of its roots?
kvasek [131]

Answer:

x^3 - 5 x^2 + 2 x + 8 = 0

Step-by-step explanation:

Solve for x over the real numbers:

x^3 - 5 x^2 + 2 x + 8 = 0

The left hand side factors into a product with three terms:

(x - 4) (x - 2) (x + 1) = 0

Split into three equations:

x - 4 = 0 or x - 2 = 0 or x + 1 = 0

Add 4 to both sides:

x = 4 or x - 2 = 0 or x + 1 = 0

Add 2 to both sides:

x = 4 or x = 2 or x + 1 = 0

Subtract 1 from both sides:

Answer: x = 4 or x = 2 or x = -1

If the parent function is square root x. describe the translation of of the fuction square root x-1
NARA [144]
The translation of a function f(x) can be described as:
f(x)->f(x-h)+k
when the functions has been translated h units to the right, and k units up.
Compare with
sqrt(x)->sqrt(x-1)+0
we see that h=1, k=0.

Thus it is a horizontal translation of 1 unit to the right. (zero unit up).
