Answer:
[-2, ∞]
Step-by-step explanation:
15 - √(x+2)
domain is any value as long as (x+2) is not-negative, since √ of a negative number has no Real solution.
x+2 ≥ 0 ⇒ x ≥ -2
A, C, D, F? Not sure but took a good guess
Answer:
x = 12
Step-by-step explanation:
5x - 7 = 3x + 17
2x -7 = 17
2x = 24
x = 12
Answer:
Step-by-step explanation:
a^2+6^2 = 23^2
a^2 = 23^2 - 6^2
a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20
From the graph given
For f(x), where x = 3, on the graph f(3) is

For g(x), where x = 3, on the graph g(3) is

Hence,

The answer is the second option
