Which parent function is f(x) = |x|?

Levart [38]

Answer:

B. The absolute value parent function

Step-by-step explanation:

$f(x)=|x|$

Referred to as absolute value, the value inside the bars is measured in terms of its distance from 0. Therefore:

$|0|=0\\|3|=3\\|-3|=3$

In essence, a negative value within the bars becomes positive, while a positive value remains positive.

Answer:

Ida makes $ 6960 in 5 weeks.

Step-by-step explanation:

Let the profit of the first week is p.

p = $ 600

Total profits of the five weeks

= p + (p + 0.15p) + (p + p +0.15 p) + (p + p + p + 0.15 p) + (p + p + p + p + 0.15 p)

= 11 p + 0.6 p

= 11 x 600 + 0.6 x 600

= 6600 + 360

= $ 6960

So, Ida makes $ 6960 in 5 weeks.
