A. Identify the error. *
san4es73 [151]

Answer:

Step-by-step explanation:

The range, in a layman language, is a set of values for which f(x) exist. Hence suppose our pre-image is 0-6,and since f(x)=20x+4 ,then

When x=0, f(x)= 4

When x=1, f(x)=24

When x=2, f(x)=44

When x=3, f(x)= 64

When x=4, f(x)=84

When x=5,f(x)=104

When x=6, f(x)=124

Hence the answer is B.
