Answer:
X = 1 , -2
Step-by-step explanation:
Given in question as,
(log4(x² + x))² = 0.25
log4(x² + x) = 0.5
Applying log base property if log(a)X = b, then X =a^b
Or, x² + x = 4^0.5
x² + x = 2
x² + x - 2 = 0
x²+2x-x-2 = 0
(x + 2) (x - 1) = 0
So, x = 1 and -2 Answer
Im not sure about the first one im probably wrong but im going with 12 and for the second one im going with 7 but im not positive with the answers <span />
Answer: I can answer 20
I think....the answer... Is......2 1/2
Hello.
So, you should already know that to find the inverse of a function you switch x and y and solve.
For f(x) = x² + 3, it's domain is all real numbers, and the range is y ≥ 3.
The inverse of f(x), it is

, and the equation is

= ±√(x - 3). It's domain is x ≥ 3, and the range is all real numbers.
There are many unique characteristics about inverses, like the values of x and y are switched, it's reflected on the line y = x, and the domain and range is switched.
So your final answer is
c.
f(x) domain: all real numbers, range: y ≥
3
domain: x ≥
3, domain: all real numbers.
Hopefully it makes sense! :)
