To find inverse
replace f(x) with y
replace all x with y and all y with x
solve for y
replace y with f⁻¹(x)


so
f(x)=1+√(1+x)
y=1+√(1+x)
x=1+√(1+y)
minus 1 both sides
x-1=√(1+y)
square both sides
x²-2x+1=1+y
minus 1 both sides
x²-2x=y
f⁻¹(x)=x²-2x


the inverse is f⁻¹(x)=x²-2x

For which function is f(x) equal to f-1(x)?
Andrews [41]
C...to show this, interchange letters: x = (y+1)/(y-1)xy-x = y + 1xy - y) = x + 1y(x-1) = x+1y = (x+1)/(x-1) ⇐ this is f-1(x) and it's identical to f(x).  Note: <span>the equal sign is missing in the definitions of the functions c. & d.</span>

Which equation represents the line is perpendicular to y=3/4x+1 and passes through (-5,11)​
melomori [17]
To find a perpendicular line, you must flip the slope over and make it negative. So, the perpendicular slope would be -4/3. Plug the point into this slope equation and solve for the y intercept. 11 = -4/3(-5) + b. b = 13/3. So, the line would be y = -4/3(x) + 13/3
