Need help on this math problem​

Answer 1

`-5, 18, √(13)`

Explanation:

We can solve the first equation, f of -3. The value of the function f is
`(1+x^2)/(x+1)`, and plugging in -3 gets us
`(1+9)/(1-3)`, 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
`|9x-15|`. Plugging in negative one third into the question gets us
`|9(-(1)/(3))-15|`

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
`√(-3-8x)`. Plugging in negative 2, we have
`√(-3-8(-2))`. Negative 8 times negative 2 is positive 16, and 16 minus 3 is 13. The answer is the square root of 13
