Step-by-step explanation:
If we have a function,
[tex]f(x)[/tex]
We can rotate the function across the x axis using the rule
[tex] - f(x)[/tex]
So we have function
[tex]f(x) = 4 {x}^{3} - 3 {x}^{2} + 8x - 6[/tex]
[tex]f(x) = - ( {4x}^{3} - 3 {x}^{2} + 8x - 6)[/tex]
[tex]f(x) = - 4x {}^{3} + 3 {x}^{2} - 8x + 6[/tex]
