Question

. Chloe performed an experiment on the amount of a certain gas that can be dissolved in water at different temperatures. Her data from the experiment is shown on the graph below. What type of function would best fit this set of data?

Answer 1

The values on the curve corresponding to the y axis are the y values

The values on the curve corresponding to the x axis are the x values

We would pick corresponding x and y values on the graph and compare them

On the graph, each small square represents 1 unit on both axes.

If x = 1, y = 1

If x = 4, y = 2

if x = 9, y = 3

We know that the square root of 1 is 1, the square root of 4 is 2 and the square root 9 is 3. This means that

y is the square root of x

The function is

`y\text{ = }\sqrt[]{x}`

Thus, it is a square root function

The first option is correct
