Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.
maks197457 [2]
F(g(x)) = [(-7x-8)/(x-1) - 8} / [(-7x - 8)/(x-1) + 7] =

[(-7x - 8 - 8(x-1)) / (x-1)] / [(-7x - 8 + 7(x-1)) / (x-1)] = (-15x) / (-15) = x.

g(f(x)) = [-7*(x-8)/(x+7) - 8] / [(x-8)/(x+7) - 1] =

[(-7x + 56 -8*(x+7)) / (x+7)] / [(x - 8 - (x + 7)) / (x+7)] = (-15x) / (-15) = x.

So since f(g(x)) = g(f(x)) = x we can conclude that f and g are inverses.

How to find the axis of symmetry if the parabola doesn't cross the y axis<br> please i need help
ale4655 [162]

Step-by-step explanation:

a parabolic graph is given by the equation ax^2 + bx + c

the axis of symmetry is equal to -b/(2a)

however it is worth noting that all parabolas have a y intercept since their domain is all real numbers.

make sure to inform me if you need further guidance.
