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.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
