I am doing Graphing Quadratic Functions. My teacher showed me how to graph problems like, f(x)=x^(1/2) + 6x +1, but the homework I got only has one variable. Like f(x)= 2x^(1/2) How would you work this.
My reality comes to a close as I once again realize that you don't love me, and even if I love you with my everything you will never care.

So, does graphing these QE mean you have to plot a graph based on the function? If yes, then it's quite easy, really.

So, in your homework,
your variable is x. Unless there is another variable like y, z etc., x, x^2, x^anything all are classified as one variable. Because all x will take the same value when you apply it/

Let f(x) = y = 2x^(1/2)
for every value of x, find a value for y. That is, plug in x=0,1,2.... and get corresponding y values. Using that plot graph.

Eg:

1. f(0) = 2(0) = 0 =y0
2. f(1)= 2(1) = 2 =y1
3. f(2) = 2(2^1/2) = 2(1.414) = 2.828

You can continue with this and plot the graph.

Thanks!

This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much all of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.
