F(x) = x2 + 1
what is f(f(
o x + 2x²+1
o x + 2x²+2
x + 2
x+1

It's x^4+2x^2+2

Step-by-step explanation:

The argument of f(f(x)) function becomes x^2+1-> F=(x^2+1)^2+1 Opening the brackets you get my answer. Not sure if O sign stood for ^4.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
