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
The answer is the second one which says 0.01 multiplied by 1,766 because in fractions 0.01 equals 1 over 100 because the 1 is in the hundredths place.
23/6
23 divided by 6 is 3 remainder 5 so it is 3 5/6
Hope this helps :)
1 kilometer = 1000 meters
1000 divided by 5 = 200
If 10 seconds x 5 = 50
Then 40 seconds x 5 = 200
40 seconds
