Question

Find f(x) -g(x)
F(x)=-8x^3+1
g(x)=2x^3+6x+7

Answer 1

Answer: -10x³ - 6x - 6

Step-by-step explanation:

      f(x) -g(x) means we will subtract g(x) from f(x)

Given:

   (-8x³ + 1) - (2x³ + 6x + 7)

Distribute the negative:

   -8x³ + 1 - 2x³ - 6x - 7

Combine like terms, simplify:

   -10x³ - 6x - 6

         f(x) -g(x) is -10x³ - 6x - 6

Answer 2

Answer:

$-10x^{3} -6x-6$

Step-by-step explanation:

The question is asking us to find f(x) - g(x). In the question it also gives the values of each as:

f(x) = $-8x^{3} +1$

g(x) = $2x^{3} +6x+7$

To find the answer, plug both of these values into f(x) - g(x):

($-8x^{3} +1$)-($2x^{3} +6x+7$)           Lets distribute the negative to $2x^{3} +6x+7$.

$-8x^{3} +1$ - $2x^{3}-6x-7$             Combine like terms

$-10x^{3} -6x-6$

Therefore, the final answer for f(x) - g(x) is equal to $-10x^{3} -6x-6$.
