Question

I need help with question #31, I don't know what do when it has a decimal number, Can explain to me how to solve that step by step.

 

In Problems 27–32, find the vertex form for each quadratic func-
tion. Then find each of the following:
(A) Intercepts
(B) Vertex
(С) Махітит or minimum
(D) Range
27. f(x) = x² – 8x + 12
28. g(x) = x² – 6x + 5
29. r(x) 3D —4x? + 16х
15 30. s(x)
— 4x? — 8х — 3
