-8 1/4, -1.5, -1/2, 1 1/2, 2.5, 3
Or -8.25, -1.5, -0.5, 1.5, 2.5, 3
Answer:
8
Step-by-step explanation:
mystery number= x
he divdes x by 2 and then subtracts 9 and gets -5. reverse the order to find x.
-5+9 which is 4 times 2 which is 8. x is 8
ANSWER
Yes,
is the restriction.
EXPLANATION
The given function is
This is a logarithmic function that is defined for
The reason is that, the logarithmic functions are not defined for negative values of x and 0.
Therefore the argument must always be positive.
When we solve the above inequality, we get,
Therefore the the restrictions is that,
This is also the same as the domain of the function.
