Explanation Given: The function is, C ( x ) = x 2 − 2 x + 12 . Formula used: Instantaneous Rate of Change: “The instantaneous rate of change for a function f when x = a can be written as, lim h → 0 f ( a + h ) − f ( a ) h , provided this limit exists”. Calculation: Substitute x = 4 in lim h → 0 f ( a + h ) − f ( a ) h and obtain the instantaneous rate of change as follows. lim h → 0 C ( 4 + h ) − C ( 4 ) h (1) Substitute x = 4 in C ( x ) = x 2 − 2 x + 12 to compute the value of C ( 4 ) . C ( 4 ) = ( 4 ) 2 − 2 ( 4 ) + 12 = 16 − 8 + 12 = 28 − 8 = 20 Substitute x = 4 + h in C ( x ) = x 2 − 2 x + 12 to compute the value of C ( 4 + h )
