The range is all Y VALUES, and the graph goes from -1 to 5, so the answer is -1≤x≤5, which I believe is C.

Two functions f(x) and g(x) are inverses if and only if:
f( g(x)) = g(f(x)) = x.
With that, we will find that the correct option is: g(x) = 2*x - 16
Let's see how to find the inverse of the given function.
The given function is: f(x) = (1/2)*x + 8
Notice that this is linear, thus, we propose an inverse that is also linear:
g(x) = a*x + b
Now we evaluate g(x) in f(x) to get:
g(f(x)) = a*f(x) + b
And that must be equal to x, so we get:
a*f(x) + b = x
a*((1/2)*x + 8) + b = x
(a/2)*x + a*8 + b = x
Then we have two equations:
(a/2) = 1, so a = 2.
a*8 + b = 0
And we know that a = 2, so we can replace that:
2*8 + b = 0
b = -16
Then the inverse function is:
g(x) = 2*x - 16

So first you write out the problem -6x-5=37 then add 5 to both sides then you'll get 42 so now your problem will be -6x=42 once you have that divide -6 on both sides and you will get x= -7
hope that helps!
Answer:
x=30 cm
y=24 cm
Step-by-step explanation:
y=24 cm
x=√(24²+18²)=√[6²(4²+3²)]=6√(16+9)=6√25=6×5=30 cm
Answer:
3⁷
Step-by-step explanation:
it's kinda messy but my step by step is in the picture. practically when you "multiply" an exponent (as long as they have the same base number) with another like 3⁴×3⁵ or (3⁴)⁵ you add the exponents together so you'd get 3⁴×3⁵=3⁹
when dividing an exponent by another exponent (with again, the same base number) you subtract the exponents like this: 3⁶÷3² or 3⁶/3² would equal 3⁴
