Question

FIND THE VERTEX please help

f(x)=x^2-10-3

Answer 1

I know that a =1
and b=-10

so then it would look like this \[x=\frac{ -10 }{ 2*(1) } =5\]

Answer 2

y=f(5)
y=(5)^2-10*5-3
then i will simplify
y=5^2-10*5-3
y=25-10*5-3 RIGHT?
SO THEN 25-10=15 AND 5-3 IS 2 RIGHT

SO THEN THE GIVEN PARABOLA IS (5, ??/)

Answer 3

y=f(5)
y=(5)^2-10*5-3
then i will simplify
y=5^2-10*5-3
y=25-10*5-3 RIGHT?
SO THEN 25-10=15 AND 5-3 IS 2 RIGHT

SO THEN THE GIVEN PARABOLA IS (5, ??/)
