Question

Given a = -4, h = -2 and k = 5, what is the equation of the graph if the parent function is y equals the square root of x

Answer 1

Remember the general form?

Answer 2

yes
f(x)=a(x-h)^2+k

Answer 3

almost...
y=a*sqrt(x-h)+k

Answer 4

so y=-4sqrt(x-2)+5 ??

Answer 5

close...
instead of (x-2) it should be (x-(-2))

understand?

Answer 6

so that's the answer? I just put
y=-4sqrt(x-(-2))+5

Answer 7

yes but (x-(-2)) becomes (x+2)
so...

y=-4sqrt(x+2)+5

Answer 8

oh yes makes sense

Answer 9

cool
