The graph located in the upper right corner of the image attached shows the graph of y = 3[x]+1.

In order to solve this problem we have to evaluate the function y = 3[x] + 1 with a group of values.

With x = { -3, -2, -1, 0, 1, 2, 3}:

x = -3

y = 3[-3] + 1 = -9 + 1

y = -8

x = -2

y = 3[-2] + 1 = -6 + 1

y = -5

x = -1

y = 3[-1] + 1 = -3 + 1

y = -2

x = 0

y = 3[0] + 1 = 0 + 1

y = 1

x = 1

y = 3[1] + 1 = 3 + 1

y = 4

x = 2

y = 3[2] + 1 = 6 + 1

y = 7

x = 3

y = 3[3] + 1 = 9 + 1

y = 10

 x     y

-3    -8

-2    -5

-1     -2

0      1

 1     4

 2    7

 3   10

The graph that shows the function y = 3[x] + 1 is  the one located in the upper right corner of the image attached.

Using the distributive property to find the product (y — 4)(y2 + 4y + 16) results in a polynomial of the form y3 + 4y2 + ay – 4y
tatiyna
If you would like to find the value of a in the polynomial, you can do this using the following steps:

(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64 = y^3 + 4y^2 + ay - 4y^2 - ay - 64

a = 16

The correct result would be 16.

Write the equation y=-1/2x+3 in standard form. how do I do this?
Lapatulllka [165]
Standard form is ax + by = c.  Begin our transformation by multiplying both sides by 2 to get rid of the fraction.  Notice that ax + by = c does not allow for fractions.  Doing that multiplication gives us 2y=-x + 3.  Now move the x over by the y by addition.  x + 2y = 3.  And there you go!

Is the square root of -11.2 a rational number?
Schach [20]
No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i.  The Sqrt(11.2) = 3.3466
so the answer is 3.3466i
