Question

Which graph represents the parent function of y=x^2 −5?

I believe it'd be the second one but how do you figure this out?

Answer 1

Hi, I don't know what answer you want but... here is a answer for anyone... hope this helps in some way! Really helpful for k12 users! And have a nice day!

so then there were 4 options:

A. -2

B.2

C. -4

D. 4

I don't know the correct answer but it is not -2 or pos 2- so not a or b. ( Like I said hope this helps in a way...)

Answer 2

from the function given:
y=x^2-5
this can be written as:
y=x^2+0x-5
writing in vertex form we get:
y=(x-h)^2+k
where: (h,k) is the vertex
y=(x-0)^2-5
thus the vertex is at (0,-5)
the parent function is y=x^2, thus the graph of the parent function is First graph
