What is the value if f(16) - f(0) hen f(x)=4x-8

Question

A.16

B.48

C.56

D.64

Answer 1

f(16) = 4*16 - 8 = 64 - 8 = 56

 

f(0) = 4*0 - 8 = 0 - 8 = -8

 

f(16) - f(0) = 56 - (-8) = 56 + 8 = 64 

 

Answer 2

f(16) means that 16 is the x value for function f(x)

 

f(16) = 4(16) - 8

f(16) = 64 - 8

f(16) =  56

 

Your answer is (C).
