Answer & step-by-step explanation:

Look at the equation: you can rewrite it as
y= x^2+4x+4 +1 = (x+2)^2+1

Now the first term of the sum is at worst 0 (when
x=-2) so the sum is no less than 1.

Correct answer is the last option. Graph is the one in the photo, the thin red line is the axis - equation
x=-2, vertex has coordinate
(-2;1), Y intersect is
(0;5) and has no x intercepts. extra points as needed if you want a more accurate graph, mine is sketched on paint so don't expect great quality
