if you vertically compress the absolute value parent function f(x)=|x| by a factor of 3 what is the equation of the new function

Sphinxa [80]

Answer:

The equation for new function is $y=\frac{1}{3}|x|$

Step-by-step explanation:

We have been given the absolute value parent function f(x) = |x| and this function is vertically compressed by a factor 3.

If we multiply the function with a constant (say a) then the parent function will get stretch/compressed vertically.

We have below conditions for vertical stretch and compression.

a > 1 => vertically stretch

0 < a < 1 => vertically compression

Hence, in order to vertical compression by a factor 3, we have to multiply the whole function by 1/3

Therefore, the equation for new function is $y=\frac{1}{3}|x|$

0 ft elevation, diver is underwater at depth of 138 ft. In this area, the ocean floor has a depth of 247 ft. A rock formations r

KiRa [710]

We know that the ocean floor has a depth of 247 ft, and we also know that the diver is underwater at depth of 138 ft, so its distance from the ocean floor will be:
 $247-138=109$ ft

Now, the rock formations rises to a peak 171 to above the ocean floor, so to find how many feet below the top of the rock formations is the diver, we are going to subtract the distance to the driver form the ocean floor from the rock formations height:
 $171-109=62$ ft

We can conclude that the diver is 62 feet below the top of the rock formations.
