Answer:
(a)Vertex = (-1, -4)
(b)x-intercepts are -2.41 and 0.41
(c)y-intercept = -2.
Step-by-step explanation:
Given the function

(a)Comparing with the vertex form of a quadratic function

The vertex of the parabola is: (-1, -4)
(b)To determine the x-intercepts, we set f(x)=0 and solve for x.

The x-intercepts are -2.41 and 0.41.
(c)The y-intercept occurs when x=0.
Therefore:

The y-intercept of the function is -2.
