Question

Write the solution to the given inequality in interval notation.

Answer 1

it should be A
because the dot at number -4 is filled dot so it symbolize with [-4 and to infinity positive number symbolize with ∞)
so the answer [-4, ∞)

Answer 2

(-4, infinity) A

Explanation:

According to the line graph, the value of the variable in question is greater than -4 since the arrow is pointing towards the positive x direction in the diagram i.e x>-4

This denote that x can take any value from -4 and above. Since there is no limit to what the value of x can be, in interval form, it can be expressed as (-4, infinity).

The interval above means the value of x is from -4 till infinity since the value of x is greater than -4 according to the graph.
