Question

A function is described as:


For the function, its range will be

• A. $18>x>128$
• B. $1>x>10$
• C. $18<x<128$
• D. $1<x<10$

Answer 1

The correct option is C $18<x<128$

Range is the set of all the possible outputs of a function.


From the table it is clearly known that the outputs are 128, 68, 200, 18.

Among them, 18 is the smallest one and 200 is largest one.

$\text{Therefore, the range of the function is:}$
$18<x<128$
