Answer:
x=2
Step-by-step explanation:
the minimum value of y is when x = 2.
Answer:
The minimum is at x = -2
Step-by-step explanation:
f(x) = (x+2)^2 -3
This is in vertex form
f(x) = ( x-h)^2 +k where (h,k) is the vertex
Since this is an upwards opening parabola the vertex is the minimum
f(x) = (x- -2)^2 -3
The vertex is (-2,-3)
The minimum is at x = -2
