Answer:
best ans is { f(x)| –∞ < f(x) ≤ 4}
Step-by-step explanation:
usually to find the range of a fn, u need to see what the value can be. the graph show only a small range of x values. but u can see f(x) is definitely <u><</u> 4. so the ans is { f(x)| –∞ < f(x) ≤ 4}

Answer:
Use the vertical line test
Step-by-step explanation:
If a vertical line crosses through the relation on the graph only once in all of the locations, then the relation is a function. However, if a vertical line crosses through the relation more than once, then the relation is not considered a function.
Answer:
8.1 ft
Step-by-step explanation:
We can use proportions to solve. Put the height over the shadow
40 ft 27 ft
---------- = -----------
12 ft x ft
Using cross products
40x = 12*27
40x =324
Divide each side by 40
40x/40 = 327/40
x = 8.1
The shadow is 8.1 ft
