Answer:
(x-1)(x^2 + 1)
Step-by-step explanation:
If the polynomial has two roots or zeros, then the least degree it can be is 2. But when x = -i is a root, generally x = i is a root too. Thus the degree here is 3. Using the roots, you can write the polynomial by finding a factor from each. The zeros are the solution to the factor. So if x = 1, it came from the factor x - 1. x = 1 is the solution because x - 1 = 0 is x = 1 solved.
When x = -i, i this is the result of a square root of a negative number. So x had the exponent 2. To write the factor for x = -i, you should write x^2 + 1. When solved x = +/-√-1 = +/- i.
The function is likely (x-1)(x^2 + 1).
Answer:
B
Step-by-step explanation:
put both sides under square root.
x^2 + y^2 = 64
sqrt ( x^2 + y^2 ) = sqrt(64)
x + y = 8
r = 8.
Answer:
17
Step-by-step explanation:
Plug the 2 in where every "x" is. Then PEMDAS
3(2+4) - 2/2
3(6) - 2/2
18 - 2/2
18 - 1
17

g(x) function
f=g, if x<0 and f>g, if x>0
