Answer:
Proved.
Step-by-step explanation:
The functions are:
1.) f(x) = 3x - 27 (* <em>I am giving an answer using this equation. Perhaps you did't copy the question well!</em>)
2.) g(x) = + 9
If two functions are inverses of each other, then:
f(g(x)) = x and g(f(x)) = x situation must be satisfied.
f(g(x)) = 3() + 27
We simply it to get;
f(g(x)) = x - 27 + 27 = x (*<em>This is correct)</em>
<em />
g(f(x)) = (3x - 27) + 9 = x - 9 + 9 = x (* <em>This is also correct!</em>)
f(x) = 2 * (1/2)^x
f(3) = 2 * (1/2)^3
f(3) = 2 * (1/2 * 1/2 * 1/2)
f(3) = 2 * 1/8
f(3) = 2/8
f(3) = 1/4
Hope this helps!
Answer:
2.50 cuz write ten and a half tally marks ten take 8.50 away
4- y=-3/2 +4
Because 2/3 has to be flipped and change the sign so it would be -3/2. But I am not sure about the y-intercept. I just went with the slope in this case.
Hope it helps!
