Ive also been stuck on this question, i really dont understand this function stuff : (

The answer is 4/5

Step-by-step explanation:

Well since we know that f(x)= x+8 and from the given values from the table we can deduce the equation for g(x) which is g(x)=12-4x. Therefore f(x)=g(x) is,

x+8=12-4x, by rearranging like terms

5x=4, dividing both sides by five

x=4/5

the two may have that, even a breakdown is probably offered
