Use the information provided to write the vertex form equation of each parabola. Please show work

1. Vertex: (9, 10), Focus(9, 19/2)

2. Vertex: (4,1), Focus:(17/4, 1)

3. Vertex:(7, 2), Focus:(15/2, 2)

4. Vertex: (1, 4), Focus:(7/8, 4)

5. Vertex:(5,0), Directrix: x= 21/4

6. Vertex: (-1, 2),
Directrix: y= 55/8

this doesn't make sense lol

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
