graphing functions - 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
enter image description here



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?
