y = −1/4x^2 + 4x − 19

1. Use x = -b/2a to find x.

x = -4/2(-1/4)

x = -4/(-1/2)

x = -4/1 • (-2/1)

x = 8/1

x = 8

2. Plug x into the function to find your vertex.

Replace every x you see in the function with 8 and do the math.

Take it from here.

State the domain of the rational function
guajiro [1.7K]

The rational function is defined as a polynomial of two parts. That is numerator and denominator i.e., denominator should not be zero.

Step-by-step explanation:

       The given function is f(x)=13/10-x

Step:1

     apply values to the term x in the given function,

     Take X=1,

      the equation becomes

      f(1)=13/10-1

      f(1)=1.444

      Take X=2,

      the equation becomes,

      f(2)=13/10-8

      f(2)=1.625

similarly,

     f(3)=1.857,

     f(4)=2.167,

     f(5)=2.60,

     f(6)=3.25,

     f(7)=4.33,

     f(8)=6.50,

     f(9)=13,

but for f(10)= 13/10-10

           f(10)=∞

    f(11)=-13,

     f(12)=-6.5,

     f(13)=4.33,.. etc

so, f(x) is positive when the X value is less than 10.

     f(x) is negative when the X value is more than 10.

but f(10)=∞ is never possible

     Therefore, all the numbers are correctly apted expect zero

Bella's Bakery charges $2.25 per cupcake
Sveta_85 [38]

Answer:

6 cookies

Step-by-step explanation:

first, find how much money they spent on cupcakes

6 × $2.25 = $13.5

then, take $13.5 and subtract that by $24

$24 - $13.5 = $10.5

so the person spent $10.5 on cookies. divide the amount per cookie by $10.5

$10.5 ÷ $1.75 = 6

so they bought 6 cookies
