What conclusion can be made?

 B) The value of k must be between 1 and 2

The function f(x) has a restricted domain [1, 2] which means

So we can only pick inputs in that interval. If x = k, then

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
