Answer:
rrtrrrfddddddddfffffffddddd
Distribute proporty
a(b+c)=ab+ac
3=a
b=40
c=7
3(40+7)=3*40+3*7
30= 3x10= 3x2x5
300= 3x100=3x10x10=3x2^2x5^2
17=17x1=17
21=3x7
Answer:
- domain: x ≥ 7
- range: f(x) ≥ 9
Step-by-step explanation:
The domain is the set of values of x for which the function is defined. Those are the values of x that make the square root argument non-negative:
x -7 ≥ 0
x ≥ 7
__
Since the square root cannot be negative, the sum of it and 9 cannot be less than 9. The range is ...
f(x) ≥ 9
