Question

Equation of the quadratic function represented by the graph is y=a(x-3)^2-1. What is the value of a?

Answer 1

I like pumpkins and you should too. The valiue of a is 2

Answer 2

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:

$y = 2 (x-3)^{2} -1$

It means that the graph of $x^{2}$ 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.
