Find f(a), f(a + h), and the difference quotient f(a + h) − f(a) h , where h ≠ 0. f(x) = 8 − 5x f(a)= f(a + h)= f(a + h) − f(a) h =

Question

I need help plugging the right information in. Thanks.

Answer 1

f(a) = 8 - 5a

f(a + h) = 8 - 5(a + h)

 

f(a + h) - f(a)

8 - 5(a + h) - (8 - 5a)

 

Now you finish.
