Write the function f(x)=x^2−4x−7 in vertex form if the vertex is (2,−11).

Step-by-step explanation:

vertex form Equation of the Parabola is

y

=

a

(

x

−

h

)

2

+

k

F

(

x

)

=

This is the vertex form Equation of the Parabola

F

(

x

)

where

h

=

2

and

k

=

−

11

and Parabola opens

u

p

since

a

=

is positive

answer: i guess 5 units?

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
