Question

HELP!!! Find the domain of the function f of x equals the cube root of the quantity x plus three, minus one.

Answer 1

A. x ≥ 0
B. All Real Numbers
C. x ≥ 1
D. x > 0

Answer 2

B. all real number

Answer 3

Thanks!!!

Answer 4

What about this?
Given a = 2, b = -2, and k = 3, what is the equation of the graph if the parent function is y equals the square root of x?

Answer 5

A. y equals two times the square root of 2x, plus 3
B. y equals negative two times the square root of 2x, plus 3
C. y equals two times the square root of negative 2x, minus 3
D. y equals two times the square root of negative 2x, plus 3

Answer 6

you need to specify what the meaning of of those constants are

Answer 7

What do you mean?

Answer 8

thats all that they gave me!

Answer 9

is it something like: y = a sqrt(bx) + k? because as far as I can tell, the position of the constants can change

Answer 10

So… what would it be?

Answer 11

the question is ambiguous. I don't know the answer

Answer 12

oh ok..
well could you help me on this?

Find the range of the function f of x equals square root of the quantity twelve x plus twenty four.
A. y ≤ 12
B. y ≥ 24
C. y ≤ 0
D. y ≥ 0

Answer 13

It's D

Answer 14

thanks!
What about this?
For the parent function y equals the square root of x, what effect does a value of b = -2 have on the graph?
A. Horizontal compression by a factor of one half and a reflection across the y-axis
B. Horizontal compression by a factor of one half and a reflection across the x-axis
C. Horizontal compression by a factor of negative one half and a reflection across the y-axis
D. Horizontal compression by a factor of negative one half and a reflection across the x-axis

Answer 15

Like I said, I can't answer unless i know what those constants mean

Answer 16

oh ya.. sorry..
For the parent function y equals the square root of x, what effect does a value of k = -3 have on the graph?
A. Horizontal shift of 3 units to the right
B. Horizontal shift of 3 units to the left
C. Vertical shift of 3 units up
D. Vertical shift of 3 units down

Answer 17

huhm... judging from the questions you're have posted so far, I am certain that k is the vertical shift. I'm not sure about a and b though. But the answer is D. vertical shift 3 units down.

Answer 18

yayyy thanks! i got a 70% but i got all the ones right that you gave me!! thank you!!!!!

Answer 19

That's what a young mathematician does lol
