Answer:
(d) y = 3x² +2x -6
Step-by-step explanation:
The equation of a parabola through thee points can be found different ways. One is to use a quadratic regression tool. Another is to write and solve linear equations in the coefficients. (3 equations in 3 unknowns).
__
Here, we can eliminate answer choices that don't work to arrive at the correct answer choice.
The point (0, -6) is the y-intercept of the function. That means the value of the constant term in the quadratic is -6. (Eliminates A and C.)
The y-values of the other two points are both greater than -6, indicating the parabola opens upward. That means the leading coefficient is positive. (Eliminates B.)
The only reasonable choice is D:
y = 3x² +2x -6

<em>Additional comment</em>
You get the same answer if you use a regression tool.
Answer:
When you multiply two numbers or variables with the same base, you simply add the exponents. When you multiply expressions with the same exponent but different bases, you multiply the bases and use the same exponent.

Answer:
9x² - 18x
Step-by-step explanation:
x(9x-18)
=> 9x² - 18x [Distributive Property]
In percent equation method , we transformed the number that we wanted to look for the percentage of into decimals and simply move the commas into two number on the right
If you get a hang on it, this method will be faster than the percent equation
hope this helps
