The standard equation for a parabola that opens upward parallel to the y-axis is x2=4ay, where a = distance from the vertex to focus. Vertex is at origin(0,0)
4a=2
a=2/4
a=1/2 or 0.5
the coordinate of the focus is (0, 1/2)
the equation of the directrix is y=-1/2

Copy and complete the statement using <,>,= |-11 |-10|
EleoNora [17]
|-11| > |-10|
this is because the absolute value is always a positive number. therefore, it is really 11 > 10.

The graph of y = f(x) is shown.<br> a) Find f(0)<br> 4-<br> 3.<br> b) Give the roots of f(x) = 0
Fiesta28 [93]

Answer:

f(0) = 2

Roots are;

-2 and -1

Step-by-step explanation:

F(0) simply refers to the y-values when x = 0

This is the point at which the graph crosses the y-axis

the value here is 2

To

find the roots of f(x) , we simply find the points at which the plot crosses the x-axis

we have this at x = -2 and x = -1

These are what represents the roots of the equation
