What is the quotient of the problem?

answer: f(x)=2x−21 is 2.

step-by-step explanation: find the difference quotient for f(x)=2x−21.

a difference quotient is given by f(x+h)−f(x)h

to find f(x+h), plug x+h instead of x:

f(x+h)=2(h+x)−21

finally, f(x+h)−f(x)h=(2(h+x)−21)−(2x−21)h=2

                        __the difference quotient for f(x)=2x−21 is

answer: 7
