Answer:
plot those dots in a x-y graph, see which one is not on the same line
the question is a bit wrong though...a function can include all of those points, but a Linear function cannot.....so if u can, tell the guy who wrote the question to rephrase it to "Linear function"
Step-by-step explanation:
Answer:
The solutions are
x=0, x=−1
Step-by-step explanation:
i looked it up i really hoped i helped but i dont think its right:(
Answer:
The equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is .
Step-by-step explanation:
A quadratic function is a second order polynomial of the form:
(1)
Where:
- Independent variable.
- Dependent variable.
, , - Coefficients.
From Algebra we understand that a second order polynomial is determined by knowing three distinct points. If we know that , and , then we construct the following system of linear equations:
(2)
(3)
(4)
By algebraic means, the solution of the system is:
, ,
Therefore, the equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is .
1/(3m)^2
1/9m^2
Hope that helps
There are infinite solutions to this , so and coordinate with than x value of 2 will lie on x=2
