I am pretty sure it is c because it inot a rihght triangle and or it does not have an hypoteneus
f(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11
f(x) = x < 1
f(-2) = -2 < 1
f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0
f(x) = x ≥ 8
f(-2) = -2 ≠ 8

The pressure at 39 feet is 2.18 atmospheres.
Step-by-step explanation:
Given function is;
P(d) = 1+d/33
We have to find the pressure at 39 feet;
d = 39
Putting in given function;
![P(39)=1+\frac{39}{33}\\\\P(39)=1+\frac{13}{11}\\\\P(39)=\frac{11+13}{11}\\\\P(39)=\frac{24}{11}\\\\P(39)=2.18\ atm](https://tex.z-dn.net/?f=P%2839%29%3D1%2B%5Cfrac%7B39%7D%7B33%7D%5C%5C%5C%5CP%2839%29%3D1%2B%5Cfrac%7B13%7D%7B11%7D%5C%5C%5C%5CP%2839%29%3D%5Cfrac%7B11%2B13%7D%7B11%7D%5C%5C%5C%5CP%2839%29%3D%5Cfrac%7B24%7D%7B11%7D%5C%5C%5C%5CP%2839%29%3D2.18%5C%20atm)
The pressure at 39 feet is 2.18 atmospheres.
