Linear functions (with the exception of f(x) = x) can have at most one fixed point. Quadratic functions can have at most two. Find the fixed points of the function g(x) = x^{2} − 20.

g(x) = x2 − 20.

x2 − 20= 0

x2 = 20

X = 20^(1/2)

X = +4.47, -4.47

two fixed points are = +4.47 , -4.47

The homework submitting program says that answer incorrect.

why .. Its a 100% correct ans ..

I showed how to calculate.

plz try once or any round figure is required in ans.

if ans is in round figure up to one decimal place then ans will be

roud(4.47) =4.5

therefor you can use ans +4.5 , -4.5

I hope it will be helpful for u

Thank you!
