If you would like to find the value of y for x = 2, you can do this using the following steps:

y = 4 x + 2 x^2 – x^3
x = 2
y = 4 2 + 2 2^2 - 2^3 = 8 + 2 * 4 - 8 = 8 + 8 - 8 = 8

The correct result would be y = 8.

\(Start \ with \ the \ original \ equation\)

\(y=4x+2x^2-x*3\) 

\(Let \ x=2\) 

\(y=4*2+2*2^2-2*3\)  

\(\fbox{y = 10}\)
