Question 622119: I have no idea how to graph with a radical. I am not sure how to write this properly but it is basically f(x)= 2 times radical X.
2 isn't a part of the radical it is multiplied by it.
f%28x%29=2sqrt%28x%29

Plug in arbitrary x values to get corresponding y values (note: f(x) and y are the same)

Since we're dealing with a square root, it makes sense to plug in perfect squares.

Plug in x = 1

f%28x%29=2%2Asqrt%28x%29

f%281%29=2%2Asqrt%281%29

f%281%29=2%2A1

f%281%29=2

So we have the point (1,2)

------------------------------------------

Plug in x = 4

f%28x%29=2%2Asqrt%28x%29

f%284%29=2%2Asqrt%284%29

f%284%29=2%2A2

f%284%29=4

So we have the point (4,4)

------------------------------------------

Plug in x = 9

f%28x%29=2%2Asqrt%28x%29

f%289%29=2%2Asqrt%289%29

f%289%29=2%2A3

f%289%29=6

So we have the point (9,6)

Keep doing this until you generate enough points. Three or four points should be enough.

Once you get your set of points, plot them on a coordinate grid. Then draw a curve (the best you can) through each point.
