Q.2) 2x + 3 is positive for what values of x ?
Q.3) For -1.5 < x < 1, y takes the form -​

Answer 1

Answer:

Heya mate your answer

Step-by-step explanation:

Q.2)Complete the square:

x² - 2x - 3 > 0

<=>  ( x - 1 )² - 4 > 0

<=>  ( x - 1 )² > 4

<=>  | x - 1 | > 2

<=>  x -1 > 2  or  x -1 < -2

<=> x > 3  or  x < -1

Q.3) {\displaystyle 1/(p-B)}{\displaystyle 1/(p-B)}, for {\displaystyle B=N(\mu ,\sigma )}B=N(\mu ,\sigma )
