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.

2.436. Rounded to the nearest whole number

natita [175]

Answer:

Step-by-step explanation:

To round off to the nearest whole number, we look at the tenth place value (the first digit after the decimal point.)

If it is a 0-4, we round the entire number down. If it is 5-9, we round the entire number up.

In this case, the tenth digit is 4. 4 is from the category 0-4, so we round 2.436 down to 2.
