How is the graph of the parent function y=x² transformed to produce the graph of y=3(x+1)²?
Anna11 [10]

Answer:

Step-by-step explanation:

Remark

Always the easiest way to study these questions is to get a graph. The one below shows

Red: y = x^2

Blue: y= 3(x + 1)^2

You will notice that (x+1)^2 shifts the graph Left -- the opposite to what you might think.

The 3 is a little harder. It narrows the red mother graph. Which choice says that?

The choice is between b and d. Why. Because the blue graph is to the left of the red one.

You have to learn the meaning of compressed. A better word might be narrows.

Answer

B

Use the frequency table to find the mean number of working TV sets in students' homes. (picture attached)
LenaWriter [7]

The correct option is :  2

<u><em>Explanation</em></u>

For finding the mean number of working TV sets, we need to <u>divide the total number of TV sets by the total frequency</u>.

Now for finding the total number of TV sets, first we will <u>multiply each number of TV sets by it's frequency and then sum up all the results</u>.

So, the total number of TV sets

=(0*1)+(1*8)+(2*9)+(3*4)+(4*3) \\\\  =0+8+18+12+12=50

and total frequency =1+8+9+4+3= 25

Thus, the mean number of working TV sets = \frac{50}{25}=2
