Question

A function g : x > 6x-8 for all real values of x, What are the elements in the domain, whose image are 10,40,-4,-6

Answer 1

Answer:

The graph of the piecewise-defined functions h:[1,3]→[2,5] defined by

h(x)={ 3x−1 if 1≤x≤2, −3x+11 if 2<x≤3,

is displayed on the left in Figure 6.5. It is clearly onto, because, given any y∈[2,5], we can find at least one x∈[1,3] such that h(x)=y. Likewise, the function k:[1,3]→[2,5] defined by

k(x)={ 3x−1 if 1≤x≤2, 5 if 2<x≤3,
