How does the graph of f(x)=3|x+2|+4 relate to its parent function

Mariana [72]

If parent functin is f(x)=|x|
it is moved to the left 2 units
vertically streched by a factor of 3
and moved up by 4 units in that order

because
to move a function to left c units, add c to every x
to vertically strech function by factor of c, multiply whole function by c
to move funciotn up c units, add c to whole function

so it is 2 to the left, verteically streched by a factor of 3 then moved up 4 units

What is the average of the sixth even number, fifth and eighth odd number after 200?

ohaa [14]

Answer:

212 is the answer !

Step-by-step explanation:

Firstly, We'll have to write all the numbers till 220 after 200 that is :

201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 ,212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 , 220 .

Here we now know the the 6th even number is 212.

And the 5th odd number is 209.

And the 8th odd number is 215.

By using the formula we can find the average that is :

212+209+215/3 = 636/3 = 212

∴ Your answer is 212 !
