• Suppose f(x)=2x−8. Determine, in a simplified form, each of the following: f(a), f(a+h), [f(a+h)−f(a)]/h?

(i) f (a) = 2a - 8 (ii) f ( a + h ) = 2 ( a + h ) - 8 (iii) f ( a + h ) - f (a) 2 ( a + h ) - 8 - ( 2a - 8 ) 2 a + 2h - 8 - 2a + 8 = 2 h
(i) f (a) = 2a - 8 (ii) f ( a + h ) = 2 ( a + h ) - 8 (iii) f ( a + h ) - f (a) 2 ( a + h ) - 8 - ( 2a - 8 ) 2 a + 2h - 8 - 2a + 8 = 2 h
