For each function, state the vertex and whether the function has a maximum or minimum value. Explain how you decided? f(x) = -(x
nordsb [41]

Answer:

maximum value at (- 1, 6 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

• If a > 0 then minimum value

• If a < 0 then maximum value

y = - (x + 1)² + 6

with (h, k) = (- 1, 6 ) and a = - 1

Thus vertex = (- 1, 6 ) and is a maximum

Select all of the factors of x3 + 5x2 + 2x – 8.
gladu [14]

The factors of this polynomial would be (x + 4)(x + 2)(x - 1).


To find these, you first have to start with long division to find the first factor. If you use x + 4 it would look like this.


\frac{x^{3} + 5x^{2} + 2x - 8}{x + 4} = x^{2} + x - 2


Now we are left with only x^{2} + x - 2. We can factor this by looking for numbers that multiply to the last number and add to the middle number. 2 and -2 multiply to -2 and add to 1. Therefore, we'll use those in parenthesis in their place.


(x + 4)(x + 2)(x - 1)
