Answer:

The domain of f is all real numbers (since it is a polynomial), hence the value of g(x) is not restricted in any way.

Answer:

$(4x - 3)(5x - 8) = 20x^2 -47x + 24$

Step-by-step explanation:

Given

$(4x - 3)(5x - 8)$

Required

Identify and correct error

The error is when the inner and outer terms are multiplied. i.e.

$4x * -8 = -32x$ not 32x

$-3 * 5x = -15x$ not 15x

So, the expression is:

$(4x - 3)(5x - 8) = 20x^2 - 32x -15x + 24$

$(4x - 3)(5x - 8) = 20x^2 -47x + 24$
