Question

What is the axis of symmetry of the quadratic function y=2(x+3)^2+5

Answer 1

Answer:

x=-3

Step-by-step explanation:

The quadratic function $y=2(x+3)^2+5$ determines the parabola which has the vertex at point (-3,5). The axis of symmetry passes through the vertex and is parallel to the y-axis. Hence, its equation is x=-3 (see attached diagram).
