Answer:

step by step explanation:

when a number is decreased by 19 %, u calculate backwards, making the % to 119% of 66. Hence it becomes 78.54 to be exact, but in the nearest tenth, it becomes 80.

The subtraction function

$(k-x)(x)$

is defined as the subtraction of the two equations, representing each function:

$(k-h)(x)=k(x)-h(x)$

So, we have

$(k-h)(x)=k(x)-h(x)=14x-2-(2x^3+4x-8)=-2x^3+10x+6$
