A. x > 0
B. x >= 0
C. y > 0
D. y <= 0

Answer 1

Answer 2

Answer 3

for domains...
a number under a squareroot cannot be negative
therefore x cannot be negative (but can be 0)

Answer 4

so is it d?

Answer 5

y values are not involved with domain
y values restrict the range of a function
therefore not C or D

Answer 6

okay thanx can u help me with 1 more?

Answer 7

sure :)

Answer 8

Using the table below, determine the corresponding parent function. Some values may be approximate.

x y
8 2.83
6 2.45
4 2.00
2 1.41
1 1.00
0 0.00

Ay=1/x.
B. y=x^2
C. y=x^3
D. y=sqrt(x)

Answer 9

hmm...
I would say a squareroot function
because when you try graphing it:
