Answer:

axis of symmetry: $x=3$ , vertex: $(3,23)$

Step-by-step explanation:

$-\frac{b}{2a}=-\frac{12}{-4}=3$

axis of symmetry(x-value of the vertex): $x=3$

input this value into the function to get the vertex

$-2(3)^{2}+12(3)+5$

$-18+36+5$

$18+5$

$23$ is the y-value of the vertex

$(3,23)$
