Find f(a), f(a + h),and the difference quotient 

f(a + h) − f(a)

h

,

 where 

h ≠ 0.

 

f(x) = 5x + 7

f(a)         =             

f(a + h) =             

f(a + h) − f(a)/h =

f(x) = 5x + 7


f(a ) = 5a + 7

f (a + h ) = 5(a + h ) + 7 = 5a + 5h + 7

( f ( a + h ) - f (a ) ) / h

( 5a + 5h + 7 - 5a + 7 ) / h

( 5a - 5a + 5h + 7 + 7 ) / h

( 5h + 14 ) / h
