Answer:
Graph of solutions of:
y = x^2 -4 (red)
x + y + 2 = 0 (purple)
Step-by-step explanation:
For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
