Question

Which equation represents the graph of f(x) = 4x3 - 3x² + 8x - 6 after a reflection over the x-axis?

Answer 1

Explanation:

If we have a function,

`f(x)`

We can rotate the function across the x axis using the rule

`- f(x)`

So we have function

`f(x) = 4 {x}^(3) - 3 {x}^(2) + 8x - 6`

`f(x) = - ( {4x}^(3) - 3 {x}^(2) + 8x - 6)`

`f(x) = - 4x {}^(3) + 3 {x}^(2) - 8x + 6`
