The graph of y = f(x) is shown below . What are all of the real solutions of f(x) =0

The answer would be c.8(2)=16-16=0 -8(2)=16-16=0

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
