Which direction does the graph of f(x) = 5x^2 − 3x − 1 open? down right up left

Which fraction below is equivalent to 10/12?

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.

Match each function with its rate of growth or decay
