Question

Which of the following is the graph of the quadratic function y=x^2+10x+16?

Answer 1

Answer:

Vertex: ( − 5 , − 9 ) Focus: ( − 5 , − 35 4 ) Axis of Symmetry: x = − 5 Directrix: y = − 37 4 Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex. Tap for more steps... x y − 7 − 5 − 6 − 8 − 5 − 9 − 4 − 8 − 3 − 5 Graph the parabola using its properties and the selected points.
