Question

Solve for x. Enter your answer in interval
notation using grouping symbols.
x² + x ≥ 2

Answer 1

Explanation:

x^2 + x - 2 >= 0

(x+2)(x-1) >= 0

This is a parabola with zeroes at -2 and + 1

everything OUTSIDE of ( and including) those zeroes is >= 0

-2 >= x >= 1

so it is the first line graph
