Question

Plot four points on the graph, the leftmost point and three other additional point

Answer 1

We have the next function

`f(x)=\sqrt[]{x}-3`

And we must graph it. We need to plot four points on the graph, the leftmost point and three other additional point

Since we have a square root of x, x just can take values equal to 0 o higher. Therefore, the leftmost point would be when x = 0.

`f(0)=\sqrt[]{0}-3=0-3=-3`

And we need to plot three other additional points. We can take values for x higher than 0

- f(4)

`f(4)=\sqrt[]{4}-3=2-3=-1`

- f(9)

`f(9)=\sqrt[]{9}-3=3-3=0`

- f(12)

`f(12)=\sqrt[]{12}-3=3.464-3=0.4641016151378`

Finally, graphing the function using the points
