Form quadratic functions given the following information:<br> Zeroes at 4 and –2, f(0)=4
laila [671]

Answer:

f(x)=-0.5x^2+x+4

Step-by-step explanation:

we know that

A quadratic function in factored form is equal to

f(x)=a(x-x_1)(x-x_2)

where

a is the leading coefficient

x_1 and x_2 are the zeroes of the function

substitute the given values

f(x)=a(x-4)(x+2)

Find the value of a

Remember that

For x=0 ----> f(0)=4

substitute

4=a(0-4)(0+2)

4=a(-8)\\a=-0.5

so

f(x)=-0.5(x-4)(x+2)

f(x)=-0.5(x^2+2x-4x-8)

f(x)=-0.5(x^2-2x-8)

f(x)=-0.5x^2+x+4

Find the total surface area of this cuboid.
-Dominant- [34]

Step-by-step explanation:

I just learned this in class lol

Find the area of all the sides.

This cubiod has 6 sides.

6 x 5 = 30

6 x 5 = 30

4 x 5 = 20

4 x 5 = 20

6 x 4 = 24

6 x 4 = 24

30 + 30 + 20 + 20 + 24 + 24 = 148

Thefore, the surface area of this cuboid is 148.

Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D
