A square root function cannot equal to all real numbers because we cant take the square root of a negative number. so B and C are already wrong.
A cubic function range is all real numbers. so y can be greater than -3 but it would also include. values lesser than -3. so D is Wrong.

A is right, the domain of a absolute value function is all real numbers. The range of a absolute value is all numbers greater than or equal to zero but if we subtract 3, it changes into all real numbers greater than or equal to -3

Vlad1618 [11]

Answer:

There is a 1/10 chance you draw an A and then D 10% chance

Step-by-step explanation:

Probablitiy of drawing a D is 1/5, If the card is not replaced, then there are only 4 cards left. Probability of drawing an A is 2/4 (1/2)

1/5 x 2/4

1 x 2 = 2 2/2 = 1

5 x 4= 20 20/2 = 10
