Given:
The quadratic function is,
[tex]f(x)=x^2+4x+3[/tex]The objective is to choose the key feature of graph which is not correct.
Explanation:
The graph of the function can be represented as,
From the graph, we can observe that,
The minimum value of the graph is (-2,-1).
The x-intercept occurs at (-3,0) and (-1,0).
But the y-intercept occurs at (0,3) instead of (0,2)
