Answer:
127 degrees
Step-by-step explanation: It is obviously an obtuse angle (more than 90 degrees), so without even looking at the tool, you can eliminate 53 degrees and 67 degrees. Now, looking at the tool, the left arrow is at 127 degrees
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) = =
