Answer:
ℝ - {(-2/3),(3/2)}
Step-by-step explanation:
We want the domain of f(g(x)). So, firstly, we have to find the domain for g(x) and, then, for f(g(x)).
- Domain of g(x): Since the expression is a fracion, we must exclude the values of x that make null the denominator. Hence,
- Domain of f(g(x)): We'll find its expression:
Now, once again, we have to exclude the values of x that make the denominator equals to zero. Thus,
Lastly, we may write the domanin of f(g(x)):
or, just writing in a shorter way:
Answer: 4 (assuming the number 4 at the end of the equation IS NOT under the radical
Step-by-step explanation:
Plug 21 in for x:
2squareroot (21-5) + 4
2squareroot 16 + 4
2(4) + 4= 12
Answer:
30
Step-by-step explanation:
1/2(12)(5)
H = -200
if h divided by 8 is equal to -25, you can multiply -25. by 8, which equals -200. Hopefully this helps!
