What is the measurement of each angle?

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
