The vertex form of a function is g(x) = (x - 3)2 + 9. How does the graph of g(x) compare to the graph of the function Rx) = x2?
O g(x) is shifted 3 units left and 9 units up.
g(x) is shifted 3 units right and 9 units up.
O g(x) is shifted 9 units left and 3 units down.
O g(x) is shifted 9 units right and 3 units down.

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.
