Step-by-step explanation:
f(x)=x^2+x
so
f(x-1) = (x - 1) ^ 2 + (x - 1)
= x^2 - 2x + 1 + x - 1
= x^2 - 3x
and
f(x+1) = (x + 1) ^ 2 + (x + 1)
= x^2 + 2x + 1 + x + 1
= x^2 + 3x + 2
now
f(x-1) + f(x+1) = 6
x^2 - 3x + x^2 + 3x + 2 = 6
2x^2 = 4
X = √2

Step-by-step explanation:
The general form of an equation of a circle with center at (a, b) and radius r is given as:
(x - a)² + (y - b)² = r²
There is no images available to help decide which circle is the right choice... But with the knowledge of what a standard circle looks like, we can make the choice.
