Wrong result in Wolfram Alpha on graph I'm learning to code in Python, so I tried to find roots and draw a graph of a function
$-(16x^2-24x+5)e^{-x}$ 1
Result i got in Python using the mat.plotlib library is this 

The problem is that Wolfram alpha is giving me the same graph, but it's incorrect. 
If you use x=1 in 1, y =1.104, not 0 as Wolfram alpha or Python are showing. I'm confused why Wolfram and even Python are plotting wrong graphs?

At the scale of your graph you can't tell $y=0$ from $y=1.104$.  The scale comes from starting the plot around $x=-5$ where the function value is almost $-80000.$  If we plot it in Alpha with a range of $0$ to $2$ we can see that at $x=1$ the value is around $1$
