Answer:
23 is the answer of the question
Answer:
Step-by-step explanation:
We can solve the first equation, f of -3. The value of the function f is 
, and plugging in -3 gets us 
, this results in 10 divided by negative 2, which is negative 5.
Now, we must solve g of negative one third. The function g is defined as 
. Plugging in negative one third into the question gets us 
9 times negative one third is -3, and -3 minus 15 is -18. The absolute value of -18 is 18.
Now, we must solve h of negative 2, and h is defined as 
. Plugging in negative 2, we have 
. Negative 8 times negative 2 is positive 16, and 16 minus 3 is 13. The answer is the square root of 13
