Answer:

D

Step-by-step explanation:

The parts of the graph below the x- axis denote where f(x) < 0

That is for

(- 4, - 2) ∪ (2, 4) → D

f(x) is not defined ( open circles ) for x = -2, x = 2, x = 5

domain is [- 4, - 2) ∪ (- 2, 2) ∪ (2, 5) ∪ (5, ∞ ) → D

What is the inverse of -9x+2
horsena [70]

Step-by-step explanation:

so,

y = -9x + 2

now we need to transform this equation that actually x is calculated out of y.

and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.

so,

y = -9x + 2

y - 2 = -9x

x = -(y - 2)/9 = (-y + 2)/9

=> for a formal function definition

y = (-x + 2)/9

Need help<br> Given u = ⟨root3, -1⟩ and v = ⟨3, –4⟩, what is u · v?
Kryger [21]

Answer:

3\sqrt{3} + 4

Step-by-step explanation:

If u = < x₁, y₁ >  and v = <x₂ , y₂ > , then

u • v = x₁x₂ + y₁y₂

Given

u = < \sqrt{3}, - 1 > and v = < 3, - 4 >, then

u • v = 3\sqrt{3} + (- 1)(- 4) = 3\sqrt{3} + 4
