Question

Given b = - 4 and h = -2, what is the equation of the graph if the parent function is y = square root of x?

Answer 1

Also could you explain it i don't really understand what it is asking

Answer 2

i believe, you are given 2 values, b and h

it then asks you to use these values to create an equation

it wants the equation to be in the form of y = sqrt(x)

Answer 3

i believe the h corresponds to an x value, and b corresponds to a y value.

it's basically asking you to do this;

y = sqrt(x - h) - b

where h and b are constants

Answer 4

someone correct me if i'm wrong, cause i dont remember the general formula of a sqrt function

Answer 5

it's kind've like y = mx + b

if i told you i wanted an equation of a line, with b = -4 and m = 2, you could do that, right?

Answer 6

same thing going on here, but instead of an equation for a line it's the equation for a square root

Answer 7

and actually, the formula should be this:

y = sqrt(x - h) + b

not - b as i had written earlier

if any of this has been confusing just ask

Answer 8

Its a little confusing because it is giving me options to answer with such as
y= sqrt4x+8
y= sqrt4x-8
y= sqrt-4x-8
y= sqrt-4x+8

Answer 9

hmm... i'm not exactly sure what it is asking then

are there any relevant equations listed somewhere in your book? such as a more general form for the sqrt function?

i think the information that's given is useless, unless we know how b and h are used
