Answer:
The graph attached represents an exponential function.
Step-by-step explanation:
An exponential function is represented by a hyperbola which shows some proportionality on the numbers.
The common thing about exponential functions is that they reach infinity.
One example of an exponential function is the graph of
The graph is a hyperbolic curve that continues without a definite value.
Another example of such a graph is the graph of :
As the value of y increases, the graph reaches closer and closer to the x- axis but takes forever to reach such a value of intersection.
We say such graphs reach infinity with the y-value.

Answer:
Each mixture has the same amount of salt for every 1 cup of water.
Step-by-step explanation:
It is provided that:
- Nia mixed 1 teaspoon salt with 3 cups warm water.
- Trey mixes 1 /2 teaspoon salt with one and 1/2 cups warm water.
The ratio of the number of teaspoons of salt to the number of cups of water is 1 : 3 in Nia's solution.
On dividing the amount of salt and the amount of water by 3, the ratio will be the same.
Thus 1 : 3 is equivalent to the ratio , which means that Nia's solution has
teaspoon of salt for every cup of water.
The ratio of the number of teaspoons of salt to the number of cups of water is in Trey’s solution.
On dividing the amount of salt and the amount of water by , the ratio will be the same.
So Trey’s ratio is also equal to the ratio .
Since each mixture has the same amount of salt for every 1 cup of water, they are equally salty and taste the same.
