If (fog)(x)=7x-1/3 and f(x)=3x+5,find g(x),where g(x)is linear

Step-by-step explanation:

Given:

and g(x) is linear.

A linear function is of the form :

Let

Then,

Comparing it with the original (fog)(x), we get

Comparing coefficient of x and constants separately

So,

understand that i don't know the answers

will someone answer his question

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
