Question

What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?

(0,-5)
(0, 3)
(0.3)
(0.5)

Answer 1

For this case we have the following function:

`f (x) = x ^ 2 + 3x + 5`

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

`f (0) = 0 ^ 2 + 3 (0) +5\\f (0) = 5`

Thus, the intersection of the graph with the "y" axis is:
`(0,5)`

ANswer:

Option D

`(x, y):( 0,5)`
