Question

find the vertex of the graph of the following equation y=x^2+8x-12
a(4,-28)
b(-4,-28)
c(-4,4)
d(4,4)

Answer 1

\[\huge\rm \frac{ -b }{ 2a }\]
formula to find vertex replace b and a by their values and then solve

Answer 2

im not good at this

Answer 3

so you should practice to be an expert
do you know what a and b values are ?

Answer 4

no

Answer 5

and your question should have = sign
after y not a plus sign

Answer 6

\[\huge\rm y = Ax^2 +Bx +C\]
quadratic equation where A and b are coefficient of variable

Answer 7

ughh I don't know how to do this

Answer 8

now tell me a = ?
and b equal what ?
