Equation of the quadratic function represented by the graph is y=a(x-3)^2-1. What is the value of a?
2 answers:
Answer:
2
Step-by-step explanation:
The graph in question is a quadratic graph that has been translated by some units, say, a units. In the transformation language, we say that the graph has been stretched by the factor of 2 like this:
It means that the graph of has been moved by 3 units to the right, stretched by the stretch factor of 2 and moved downwards on y-axis by 1 unit.

Step-by-step explanation:
In a quadratic equation in the Standard form
You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero: ).
You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:
Therefore, you can identify that the values of "a", "b" and "c" are the following:
