Answer 4

ok. then do you know the graph of
\[\sqrt{x}\]

Answer 5

no I don't :/

Answer 6

@nikato

Answer 7

actually if you dont know anything, you can j ust plug in numbers for x and find y and then graph

Answer 8

for example,
you are given \[\sqrt{x+1}\]

Answer 9

Answer 10

and you know some perfect square like 0,1,4,9
so to make your life easier find values where

x+1=0
x+1=1
x+1=4

Answer 11

then after you find those values of x, you can plug it pack into your equation to find y.
and you'll have a few points to help you roughly sketch your graph

Answer 12

this is how the graph should look like, I just don't know how to get it too look like that

Answer 13

when h(x) = 0
-2 = -rt (x + 1)
divide by -1 and square each side
4 = x + 1 so x = 3
point (3,0)
when x = 0
H(0) = 2 - rt (0 + 1) = 2 -1; 2 + 1
points (0,1) and (0, 3)
