What is the focus of the parabola?

y=−14x2−2x−2

enter your answer in the boxes.

Step-by-step explanation:

Given is a parabola

Let us rewrite this in vertex form

Hence vertex =

Axis of symmetry is

a=

Hence focus would lie on the line of symmetry at a distance of a from vertex

So focus =

If this is for k12 I took the test and the right answer was (-4, 1)

Step-by-step explanation:

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
