Answer:
Explanation:
Given the equation:
We evaluate two points on the line below:
From the given options, the graph that contains the points (0,0) and (1,3) is Graph D.
The correct answer is Graph D.
If f(x) is the inverse of g(x), then f(g(x))=f(g(x))=x
or we can do it the hard way and solve for the inverses (I'm too lazy to do that)
I'm assuming you means g(x)=(x-4)/2
so
show that f(g(x))=g(f(x))=x
first do f(g(x))
f(g(x))=2((x-4)/2)+4
f(g(x))=x-4+4
f(g(x))=x
g(f(x))=(2x+4-4)/2
g(f(x))=(2x)/2
g(f(x))=x
both equal x and x=x so f(g(x))=f(g(x))=x
they are iinverses
if you did want to solve then
do, f(x)=y, then swtich all x and y then solve for x
example
f(x)=2x+4 then y=2x+4 then x=2y+4 then x-4=2y then (x-4)/2=y=g(x)
then reverse it to get the other inverse thing
<span>subtract 16 from both sides, you will get
12x= 180
divide by 12
x=15 ft.
Answer: width = 15 ft.; length = 30 ft.
