Answer:
not a function
Step-by-step explanation:
When any x-value (input) maps to more than one y-value (output), the relation is <em>not a function</em>.
Here, 9 maps to 2 different y-values (4 and 5), so the relation is not a function.
42 cubic units
7 x 3 x 2 = 21 x 2 = 42
x = 22°
158 + x = 180
x = 180 - 158
x = 22
