1. Verify that the functions...

1. Verify that the functions f and g are inverse of each other by showing that f(g (x) ) = x and g (f (x) ) = x. Give any values of x that need to be excluded.

f(x) = x – 5 / 2x + 3; g(x) = 3x + 5 / 1 -2x

2. Difference quotient

If f(x) = loga x, show that f(xa) = af (x)

I will rewrite:

(If f(x) = log sub a x, show that f(x super a) = αf(x))

f(x) = x – 5 / 2x + 3; g(x) = 3x + 5 / 1 -2x

2. Difference quotient

If f(x) = loga x, show that f(xa) = af (x)

I will rewrite:

(If f(x) = log sub a x, show that f(x super a) = αf(x))
