Answer:
f^-1(x) = 9x+18
Step-by-step explanation:
To get the inverse of a function, we exchange x and y then solve for y
y = 1/9x -2
Exchange x and y
x = 1/9y -2
Add 2 to each side
x+2 = 1/9y-2+2
x+2 = 1/9y
Multiply by 9
9(x+2) = 9*1/9y
9x+18 = y
f^-1(x) = 9x+18
Answer:
135°
Step-by-step explanation:
octagon is a 8-sided polygon, and the sum of angles is 360°
By dividing 360/8=45°, which means each 45° rotation maps the octagon onto itself i.e 45°+45°+45°=135°
135° lies between 95° and 135°
