Answer:
b =
Step-by-step explanation:
Using the discriminant for nature of roots ( x- intercepts )
If b² - 4ac = 0 then roots are real and equal ( that is only 1 x- intercept )
Given
f(x) = x² - 2bx + b² + 2b - 1
with a = 1, b = - 2b and c = b² + 2b - 1, then
(- 2b)² - 4(b² + 2b - 1) = 0 ← distribute and simplify left side
4b² - 4b² - 8b + 4 = 0
- 8b + 4 = 0 ( subtract 4 from both sides )
- 8b = - 4 ( divide both sides by - 8 )
b =

<u><em>Answer:</em></u>5</span>⁵/⁴<span>
<u><em>Explanation:</em></u><u>Before we begin, remember the following:</u></span>
<span> = x</span>¹/ⁿ

The root form is known as the radical form while the power form is the rational form
<u>Now, for the given:</u>We want to convert from the radical (root) form to the rational (power) form.
The given is:
4th root of 5</span>⁵<span>
Applying the above rules, we will find that the rational form is:
5</span>⁵/⁴<span>
Hope this helps :)

Answer:
For this case the amplitude is given by:
A = (l-5l + 3) / 2
A = 8/2
A = 4
The middle line is given by:
y = -1
The period of the function is given by:
T = l x2 - x1 l
T = l 0 - 2pi l
T = l - 2pi l
T = 2pi
Answer:
Amplitude: 4; period: 2π; midline: y = -1
Step-by-step explanation:
pi
the answer is 7 - 8/x + 1.
