## Function is Not Graphing in the Range I want it to

Question

```
x = [np.sqrt(.16425), 0.54455260535599315,
0.70689815390903377,
0.90923319341079933,
0.82807306440917394,
1.1290283433111854]
x
y = [0.8187249999999999,
1.0933652892561987,
1.419317391304348,
1.8247052631578946,
1.6618111111111107,
2.2666052631578943]
def graph(formula, x_range):
x =np.array(x_range)
y =eval(formula)
plt.plot(x, y)
graph('0.00030796 + 2.00697*x', range(np.divide(1,2),2))
plt.scatter(x,y)
plt.xlabel('Sqaure Root of Length (m^(1/2))')
plt.ylabel('Approximate Average Period (s)')
plt.show()
```

All I am trying to do is plot some data points and a theory line to accompany it, but my range only accepts integer values so I have no clue how to make a nice graph with a nice range to show my data points and the theory line through them. Can someone help me out?

You code has more issues than what you are describing. Here is an implementation that works.
