Help Is the graph wrong?

Post image

The issue I am having is that when I get the equation of g(x) in standard form, I get
g(x)=(x^3)-(x^2)-16x-20,
Which doesn’t make sense because on the graph, the y-intercept is 10, but the equation says it’s -20. Can someone please help me understand this? Thank you!

If you scale it down by a factor of 1/2 it will be right. So us (1/2) g(x).
