Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 8 units below the vertex of the graph of g(x). Which pair of functions could have been used to create the graphs of g(x) and h(x)?

Question 15 options:

h(x)=x2−8 and g(x)=x2

h(x)=x2+8 and g(x)=x2

h(x)=(x−8)2 and g(x)=x2

h(x)=(x+8)2 and g(x)=x2

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
