The vertex is the center point of the line or the axis of symmetry
So your answer should be (-2, -5)
Assuming you meant

Then you can compose the function g(x)

With the function

Because f (g(x) ) means that you first find (calculte)

and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
First, subtract to get the difference.
2.85 – 2.78 = 0.07
Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).
Hope this helps!
