Answer: the maximum is (-2,5 )and the equation for the axis of symmetry is x = -2
Explanation if you want:
for the min and max: when a quadratic has a maximum point, that is the largest point that it will ever be at. When it has a minimum, that is the smallest.
- the +5 tells us that we have an upward movement of 5. The +2 means we actually move to the point -2. bc: (x+2)=0 = -2
- so, from our initial function, those are the changes.
for the axis of symmetry: basically, this is the line that splits the graph into two equal parts.
- it is the line that goes through the vertex (which we already know is (-2,5).
there u go
