The answer to your question is C.48
The domain would negative infinity to positive infinity . Domain would be the smallest through the largest possibly value of X. If you also need the range it’s ( -4,infinity]
Answer:
The answer is the "Null hypothesis and Alternative hypothesis".
Step-by-step explanation:
The null hypothesis is almost like a hypothesis test, which indicates the certain demographic characteristics which aren't varied.
The alternative presumption will be that the hypothesis besides making predictions is opposite to the void assumption. Its posts are generally taken as a result of a meaningful effect.
Difference:
The null hypothesis is indeed a gross generalization, which specifies there is no relation between different phenomenons under evaluation. There is no association between the two groups. An alternate solution hypothesis is a statement, that defines there is a relation between different chosen variables in this study.

Answer: Choice B. x = 4 and x = 3</h3>
Work Shown:
x^2 - 7x = -12
x^2 - 7x + 12 = 0
(x - 3)(x - 4) = 0 ... see note below
x - 3 = 0 or x - 4 = 0
x = 3 or x = 4
Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.
A prime polynomial is one that can only be divided by itself and 1. Let's check it option.
A. x³-bx²
This polynomial can be divided by itself, 1, x and x². So it can't be prime.
B. x²-4x-12
This polynomial represents the standard form of a second order polynomial. This means that it is a parabolla. A polynomial of this form can be divided by (x-a) where "a" is the value of its roots. So it can't be prime.
C. x+8xy³
This polynomial can be divided by x, 1 and itself, therefore it can't be a prime.
D. x²-b³
This polynomial can only be divided by 1 and itself. So this is the correct answer.
