Find the limit x³ - 1/ x² - 1 as x approaches 1.

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)

If f(x)=x+7 and g(x)=1/x what is (fog)(x)

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
