Question

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

A
(0,-5)
(0, -3)
(0,3)
(0,5)

Answer 1

(0, 5 )

Explanation:

Where the graph crosses the y- axis the x- coordinate of the point is zero

Let x = 0 in the equation to find y- intercept

f(0) = 0² + 3(0) + 5 = 0 + 0 + 5 = 5 ← y- intercept

The coordinates of the y- intercept are (0, 5 )

Answer 2

(0,5)

Explanation:

Y intercept is where line touches y axis so x = 0.

(0,5) since it's only 5 and the others don't count.
