One way is to solve for the invers of the first function
remembe, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with f⁻¹(x)
A.
f(x)=x/2+8
y=x/2+8
x=y/2+8
x-8=y/2
2x-16=y
f⁻¹(x)=2x-16
nope, not A
B.
f(x)=3x³+16
y=3x³+16
x=3y³+16
x-16=3y³
(x-16)/3=y³
∛((x-16)/3)=y
f⁻¹(x)=∛((x-16)/3)
nope, not the same
not B
C.
f(x)=18/x-9
y=18/x-9
x=18/y-9
x+9=18/y
y(x+9)=18
y=18/(x+9)
f⁻¹(x)=18/(x+9)
correct, the answer is C
answer is C
Answer:
900 miles
Step-by-step explanation:
Given:
Total time taken by Kris is 14 hours.
Speed of Kris is, Speed = 75 mph
Time spent while taking a break is 2 hours.
So, time Kris drove his vehicle is given as the difference of total time and time spent in break. Therefore,
Actual time of driving = 14 - 2 = 12 hours.
Now, distance traveled is given as the product of speed and time of driving.
∴ Distance = Speed
Time
Distance = 
Therefore, Kris drove 900 miles.
