4. The graph of h(x) = x^2 was transformed to create the graph of k(x) = -4x^2? Which of these describes the transformation from

Viefleur [7K]

Answer:

A. A reflection over the x-axis and a vertical stretch.

Step-by-step explanation:

Let $h(x) = x^{2}$ , to obtain $k(x) = -4\cdot x^{2}$ , we need to use the following two operations:

(i) Vertical stretch

$g(x) = k\cdot f(x)$ , $k\in \mathbb{R}^{+}$

(ii) Reflection over the x-axis

$g(x) = -f(x)$

Let prove both transformations in $h(x)$ :

Step 1 - Vertical stretch ( $k = 4$ )

$h'(x) = 4\cdot x^{2}$

Step 2 - Reflection over the x-axis

$k(x) = -4\cdot x^{2}$

Hence, correct answer is A.

The following chips are placed in a bucket: 5 red, 3 yellow, 4 blue, and 1 green. One chip is randomly selected from the bucket.

maria [59]

So,

If we add them together, we get
5 + 3 + 4 + 1 = 13

Since there are 4 blue chips, the probability would be 4 out of the total number of chips, or 4/13.

$The \ probability \ of \ the \ random \ selection \ of \ a \ blue \ chip \ is \ \frac{4}{13} .$
