This is an example of the quotient of powers property and tells us that when you divide powers with the same base you just have to subtract the exponents. When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1.
In a quadratic function, the leading coefficient is
, i.e. the coefficient of
, and the constant term is
, i.e. the coefficient without any power of
.
So, if you want leading coefficient 2 and constant term -3, your function needs to be like
for any value of . Among your options:
- The first is not a quadratic (it starts with
)
- The second has leading term -3 and constant term 2
- The third is not a quadratic (same as the first)
- The last is correct.
Answer:
The average rate of change is
Step-by-step explanation:
Given function that shows the population of a culture of cells,
Where, t represents the number of weeks.
Thus, the average rate of change in the population over the interval [0,24],
From equation (1),
