Answer:

bottom of graph will move from (0,0) to point (1,3) after transformation

Step-by-step explanation:

given

original : f(x) = x^{2}

transformed; g(x) = (x-1)^{2} + 3

look at this way g(x) =  (x-h)^{2} + k

if (x-h), h>0, move h units to the right

if k>0, move k units up

the bottom of the graph will be at point (1,3)

When results from a scholastic assessment test are sent to test-takers, the percentiles associated with their scores are also gi
hram777 [196]

Answer:

The correct option is (D).

Step-by-step explanation:

Percentiles are statistical measures that are used to interpret data. It represents the data value which is more that a specific percentage of the data set.

The <em>n</em>th percentile of a data set is the value that is more that <em>n</em>% of the data set.

⇒ It is provided that a test-taker's score was at the 94th percentile for their verbal grade.

This statement implies that the test taker scored a mark more than 94% of the other test-takers, i.e. he\she performed better than 94% of the other test-takers in the verbal grade.

⇒ Also the test-taker's score was at the 16th percentile for their quantitative grade.

This implies that the test taker scored a mark more than 16% of the other test-takers, i.e. he\she performed better than 16% of the other test-takers in the quantitative grade.

Thus, the correct option is (D).

Y=x+1<br> y=x^2-1<br><br> please help i don't understand
ololo11 [35]

ANSWER

The solution is

(x=1,y=2),(x=2,y=3)


<u>EXPLANATION</u>

We have

y=x+1---(1)

and


y=x^2-1---(2)


Let us substitute equation (1) in to equation (2). This gives us,

x+1=x^2-1(2)

We rewrite this as a quadratic equation as the highest degree is 2.

x^2-x-1-1=0

This implies that


x^2-x-2=0


we factor to obtain,


x^2+x-2x-2=0


x(x-1)-2(x-1)=0


(x-1)(x-2)=0


This means,

(x-1)=0\:\: or\:\:(x-2)=0

x=1\:\: or\:\:x=2


We substitute this values into any of the above equations, preferably equation (1)


When, x=1, y=1+1=2


When, x=2, y=2+1=3


The solution is

(1,2),(2,3)

So you would use the equation y=mx+b
