Question

thanks

Answer 1

Is this FLVS?

Answer 2

Im doing it rn

Answer 3

alg 1 sem 2 mod 7

Answer 4

im way behind, was on vacation

Answer 5

maybe, one sec

Answer 6

divide the coefficient of t by 2
6 / 2 = 3

so we have

f(x) = (t + 3)^2 - 9 - 20
= (t + 3)^2 - 29

Answer 7

- thats vertex form

Answer 8

ok the general form for veretx is (x - a)^2 + b where (a,b) is the coordinates of the vertex

so comparing with our result the vertex is at (-3,-29)

Answer 9

the coefficient od t^2 is positive so that makes the vertex a minimum.

Answer 10

the axis of symmetry is the vertical line going through the point (-3,-29)
can you tell me the equation of that line?

Answer 11

yes you can work it out that way.
but easier way is to note that vertex has t = -3

so axis of symmetry is t = -3
