Answer:
Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x = (x) , thus
(x) =
Evaluate g(3) and substitute the value obtained into (x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) = =
Answer:
(5/2,-5)
Step-by-step explanation:
plug in zero for each of the variables to get the other one
2x-0=5
2x=5
x=5/2
2(0)-y=5
-y=5
y=-5
