Explain how to find the unit rate of water to vinegar

Helena uses double the amount of water to the amount of vinegar.

Step-by-step explanation:

Thus, Helena uses double the amount of water to the amount of vinegar.

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
