The answer for this problem is D
Answer:
f^-1(x) = (x -2)/3
Step-by-step explanation:
To find the inverse function, swap x and y, then solve for y.
y = 3x +2 . . . . given function
x = 3y +2 . . . . inverse relation
x -2 = 3y . . . . subtract 2
(x -2)/3 = y . . . divide by 3
f^-1(x) = (x -2)/3 . . . . in functional form
Answer:
f(3)=1
Step-by-step explanation:
take f(x)=2(x)-5
put a three wherever you see an x in parentheses
f(3)=2(3) - 5
simplify
f(3)=6-5
simplify
f(3)=1
answer:f(3)=1
