Question

Find the difference quotient and simplify your answer. f(x)=((4)/(x+1), f(x)-f(7))/x-7, x≠7

Answer 1

f(7)=?

Answer 2

i goingtogive you more clear

Answer 3

([(4)/(x+1)]-[(4)/7+1)])/(x-7)

Answer 4

\[\dfrac{\frac{4}{x+1}-\frac{4}{8}}{x-7}\]right?

Answer 5

yeah like that

Answer 6

solve the big numerator first. what do you get? (Hint: make them have the same denominator). I mean
