Answer:

See below

Step-by-step explanation:

The roots are:

3, 3, 2 - 3i, 2 + 3i (conjugate of 2 - 3i should be added) and the leading coefficient is - 5

The polynomial is:

-5(x - 3)² (x - [2 - 3i]) (x - [2 + 3i]) =
- 5(x² - 6x + 9) (x² - 4x + 13) =
-5(x⁴ - 10x³ + 46x² - 114x + 117) =
-5x⁴ + 50x³ - 230x² + 570x - 585

Find the zeros of the function. Write the smaller solution first, and the larger solution second. f(x)=(x+8)^2−1

BartSMP [9]

Answer:

zeroes: x = -9 and x = -7

Step-by-step explanation:

f(x)=(x+8)^2−1

A "zero" refers to when the y-value on the graph is zero.

0 = (x+8)^2 - 1

1 = (x+8)^2

+ or - 1 = x+8

so break them apart into two equations

x+8 = 1 OR x+8 = -1

x = -7 OR x = -9

You can plug both back in to check that the equation works!

Look at where the lines intersect each other, if they do then you can use one of the coordinates. the lines that don’t touch means no solution

Can you guys help me??????? really want to know what to do :)

Answer and Step-by-step explanation:

In the picture:

The graph is shaded to the right, because everything that is above -2 is allowed, so the shaded region is what is allowed to be true in this inequality.

The line is dotted because the inequality is only using greater than or less than, and not greater than or equal to, or less than or equal to.
