Question 44776: what is the inverse of f(x)= 2x+1 ?
what is the inverse of f(x)= x(to the second power) -3?
Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
f(x) = 2x + 1
y = 2x + 1
x = 2y + 1
x - 1 = 2y
0.5x - 0.5 = f^-1(x)
f(x) = x^2 - 3
y = x^2 - 3
x = y^2 - 3
x + 3 = y^2
+- sqrt(x + 3) = f^-1(x)
