Answer:
the domain for this parabola is all real numbers
Answer:
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Step-by-step explanation:
A survey is being conducted to determine how a city's residents feel about building a new youth center.
They are considering to survey 50 random children at a local elementary school.
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Moreover, it is likely that the students of elementary school might not even have any interest in youth center so results would be biased.
Therefore, it is suggested to include a variety of samples that is surveying different age groups that covers all of the community.
Answer:
Step-by-step explanation:
Quadratic function-
It is a function that can be represented by an equation of the form 
, where 
In a quadratic function, the greatest power of the variable is 2.
As in the first option the highest power is 3, so it is not a quadratic function.
Even though the power of x is 2 in the third option, but as it is in the denominator, so the overall power of x becomes -2. Hence it is not a quadratic function.
As the coefficient of 
is 0 in case of fourth option, so it is not a quadratic function.
Equation in option 2 satisfies all the conditions of quadratic function, hence it is the quadratic function.

Answer:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3 Solve each equation for a.
2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3
Cross multiply: 2b3 = 4b2 Divide both sides by b2
2b = 4 a = 2/4 = 1/2
b = 2
y = 1 (2)x
2
