Answer:
The equation is .
Step-by-step explanation:
When we say that a variable varies directly as another variable, or is directly proportionate to another variable, we mean that the variable changes with the same ratio as the other variable increases.
This kind of correlation can be represented as a linear function that passes through the origin, the equation of which is of the form . The two variables we are considering are <em>x</em> and <em>y</em>, while <em>k</em> is called the constant of proportionality.
We know the constant of proportionality k = -3, applying the above definition we get that the equation is .

Answer:
Graph A is the correct graph for the transformations shown in the function g(x)
Step-by-step explanation:
Within the function
We can see two transformations occur from the parent function. The first is a slide along the x-axis and the second is a slide along the y-axis
Under the radicand we see that it is x+2. This means that the function has been shifted 2 units left from the parent function
As there is a -4 outside of the radicand, it would mean that the function has been shifted 4 units down as well.
This means that we are looking for a function centered around the point (-2,-4)
