1. I could use some guidance with a question that says "Find f^-1(3)"
Given: F(x)= 3 + x^2 + tan(PIx/2), where -1 < x < 1
I know I should find the inverse first then plug in 3 and solve. I just cannot get the inverse...
First swap x and y, but after that I cannot think of how to isolate y. I have...
x = 3 + y^2 + tan(PIy/2)
Same problem thing with
2. y = 3 + x + e^x find g^-1(4)
what is "e" just a normal variable? The book says the answer is zero...
Thanks a bunch!
