Answer:
f^-1(x) = (x +4)/3
Step-by-step explanation:
The inverse function is found by swapping x and y, then solving for y.
y = 3x -4 . . . . . function y = f(x)
x = 3y -4 . . . . . inverse relation
x +4 = 3y . . . . add 4
(x +4)/3 = y . . . divide by 3. This is the inverse function
f^-1(x) = (x +4)/3
Answer:
B. f and g are reflections of each other about the x-axis.
Step-by-step explanation:
I calculated it logically
The linear approximation means that you assume the function is linear. So, just do :
f(5) + f'(5) (x-5)
This works out, in this specific case
3 + 4 (- 0.2)
Hope this helps
