Question

f(x)=4x^2-40x+104
vertex?
line sym?
min/max?

Answer 1

(5,4)?

Answer 2

since the function is written in f(x) = ax^2 + bx + c
the x coordinate of the vertex is obtained by -b/(2a)
the vertex is (-b/(2a), f(-b/(2a))

Answer 3

can you identify
a=
b=
c= (not needed)

Answer 4

graph look like this, roughly
