Answer:
B?
Step-by-step explanation:
I think is B because solar power never run out.
（For the next 5000000000 years at least...）
None of the two answer choices are correct, answer is none of the above
simplify by multiplying by 2 we get 10g+6h+8. neither of the two choices match
G(x) would involve a translation left 1 and up 1.
g(x) is written in vertex form, which is
g(x) = a(x-h)²+k, where (h, k) is the vertex. Since
g(x) = 4(x-8)²+9, the vertex is at (8, 9). Comparing this to the vertex of f(x), which is at (9, 8), it is left 1 and up 1.
<u>Answer:</u>
The correct answer option is: Each x value has one and only one y value.
<u>Step-by-step explanation:</u>
A relationship from a set of inputs to a set of outputs where each input has exactly one corresponding output value is said to be a function.
Here, we are given 
which happens to be a function as no x value is repeated and there is only one corresponding y value to it.
Therefore, option c is the correct answer.
