Answer
q1.
Given:
Rewrite this function in the way as;
then;
and
q2.
Given the function:
and
Confirm f and g are inverses by showing f(g(x)) =x and g(f(x)) =x
First show f(g(x)) =x
f(g(x)) = 9(g(x)) + 3
Substitute the function g(x) we have;
or
= x -3 + 3 = x
f(g(x)) =x
Similarly show that: g(f(x)) =x
Substitute the value of function g(x) we have;
Simplify:
hence proved!
Therefore, f and g are inverse of each other after showing f(g(x)) =x and g(f(x)) =x
Answer:
25
Step-by-step explanation:
Move the negative sign to the left:
5y - 6/5y
7 is digit for hundred thousands and 6 is for ten thousands so the answer is 800,000
