Answer:
(c) P(x) = x^4 +3x^3 -10x^2 -30x
Step-by-step explanation:
If the polynomial has integer coefficients, its complex or radical roots come in conjugate pairs. That is, -√10 is also a root. The four roots mean the polynomial has degree 4. That eliminates all but answer choice C.
Each root 'a' gives rise to a factor (x -a), so the factored polynomial is ...
P(x) = (x -0)(x -(-3))(x -√10)(x -(-√10))
P(x) = x(x +3)(x² -10) = x(x³ +3x² -10x -10)
P(x) = x^4 +3x^3 -10x^2 -10x
Answer:
Hisoka FS no doubt he is most def BRAINLIEST???
The answer is $906
hope i helped
plz make me the brainlest plzz i really need it
Anything added or subtracted from x INSIDE a perentesis will shift our graph to the left (if subtracted) or to the right (if added).
we need to find Ks that shift our graph to the right (we need Ks that are ultimately ADDED to x).
so just plug in the options and see which ones work. hint: they are -130, -458, -214
(keep in mind that there is a negetive before k in f(x) so any negetive will be positive and any positive will be negetive
Answer: Option 4: -2sin(x + pi/2) - 1
Step-by-step explanation:
When this equation is graphed, the y-intercept is -3 which is what the image shows. None of the others have a y-intercept at -3.
Hope this helps!
