See the graph

Work Step by Step

Given: $y=3(x+4)^2+7$ The function is in vertex form $y=x(x-h)^2+k$ with $a=3, h=-4,k=7$ Hence, the vertex is $(-4,7)$ The axis of symmetry is $x=-4$ Find some other points: $x=-6 \rightarrow y=19$ $x=-5 \rightarrow y=10$ $x=-3 \rightarrow y=10$ $x=-2 \rightarrow y=19$
