For this case we have the following function:

[tex]f (x) = x ^ 2 + 3x + 5[/tex]

We must find the intersection of the graph with the axis "y", for that we do[tex]x = 0[/tex]:

[tex]f (0) = 0 ^ 2 + 3 (0) +5\\f (0) = 5[/tex]

Thus, the intersection of the graph with the "y" axis is: [tex](0,5)[/tex]

ANswer:

Option D

[tex](x, y):( 0,5)[/tex]
