All positive real numbers. in this function, the domain is the radius. all real numbers includes negative numbers, and u cant have a negative distance. you also cant have a radius of 0 because the circle wouldnt exist. and u can have a fraction domain, so A is the answer
Multiply both sides by a
(a + 4)a = -3
Regroup terms
a(a + 4) = -3
Expand
a^2 + 4a = -3
Move all terms to one side
a^a + 4a + 3 = 0
Factor a^2 + 4a + 3
(a + 1)(a + 3) = 0
Solve for a
<u>a = -1, -3</u>
