Question

Graph y = ½ x2 and its inverse.

List the point(s) of intersection.

*Do not use (0, 0)

Answer 1

x=.5y^2

y^2 = x/(0.5)

f^-1(x) = y=sqrt(x/0.5)

Answer 2

-1, 1)


(2, 2)

(1.51, 1.51)

(-1.25, 1.3)

Answer 3

f(x) = ½ x2 | f^-1 (x)= sqrt(2x)
x=-2 y=2 | x=-2 y= No value
x=-1 y=1/2 | x=-1 y= No value
x=1 y=1/2 | x=1 y= 1.414
x=2 y=2 | x=2 y=2

Answer 4

o.o

Answer 5

Interception at (2,2) because both have the value
