Answer:

Step-by-step explanation:

all we have to do is plug in 2 for x into the equation:

-8(2) + 5 -2(2) -4 + 5(2)

-16 + 5 -4 -4 + 10

-11 -8 + 10

-19 + 10

the answer is

-9

to simplify the equation we’ll combine like terms

-8x + 5 -2x -4 + 5x

-10x + 1 + 5x

-5x + 1

now we’ll plug in 2 for x

-5(2) + 1

-10 + 1

the answer is still

-9

F(x)=1/x and g(x)=x-4<br> Can you evaulate (g o f)(0) explai sn why or why not
Ostrovityanka [42]

Hello from MrBillDoesMath!

Answer:

 (g o f)(0) cannot be evaluated

Discussion:

(g o f)(0) = g ( f(0))  if it exists but f(0) is not defined (as division by zero is not defined) so   (g o f)(0) cannot be evaluated

Thank you,

MrB
