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

)

=

x

2

−

4

x

−

7

=

=

−

11

This is the vertex form Equation of the Parabola

F

(

x

)

where

h

=

2

and

k

=

−

11

and Parabola opens

u

p

since

a

=

1

is positive

y do u put "subscirbe to ence" on a app for ppl who need with their work?

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
