Answer:
Option C) Quadratic regression model
Step-by-step explanation:
Quadratic regression model
- It is regression model in which states a non-linear relationship between the independent and dependent variables.
- It includes the dependent variable and the square of the independent variable.
where x is the independent variable and is the dependent variable.
- It is also referred to as second-order polynomial model.
- It is used when the data shape resembles to a parabola.
Thus, the correct answer is
Option C) Quadratic regression model
Answer:
The first answer is the correct one
Answer:
5 or -5
Step-by-step explanation:
3+2=5
-1(3+2)=-5
Which represents the polynomial written in standard form?
8x2y2 – + 4x4 – 7xy3
<span>Write the quadratic function in the form:
f(x) = a(x-h)</span>²<span> + k
Given Function:
f(x) = 3x</span>²<span> + 18x + 28
Using the completing square method:
</span> f(x) = 3(x² + 6x + 28/3)
f(x) = 3(x² + 6x + (3)² - (3)² + 28/3)
f(x) = 3[(x+3)² - (3)² + 28/3]
f(x) = 3[(x+3)² - 9 + 28/3]
f(x) = 3[(x+3)² - 27/3 + 28/3]
f(x) = 3[(x+3)² - 1/3]
f(x) = 3(x+3)² - 1
Therefore,
The vertex is (h,k) = (-3,-1)
