i agree with @3mar 
summat missing here

what are b and h?

angelemily · Answer

no graph came with the question tho.

danjs · Answer

'a' would stretch or compress the function vertically
'b' would stretch or compress horizontal
'h' shift graph left or right
'k' shift up or down

danjs · Answer

$$a*f[b(x-h)]+k$$

danjs · Answer

for the function square root of x...

$$\large y = a*\sqrt{b(x-h)}+k$$

@AngelEmily 
the question said: see the attach.


Fix it, please

danjs · Answer

b=2 and h=8 ,

if 'a' is not given, assume it is a=1 
if 'k' is not given, assume it is k=0

$$\large y=\sqrt{2*(x-8)}$$

angelemily · Answer

ok so would my answer be $$y= \sqrt{2x - 16}$$

3mar · Answer

DanJS explained it very well.
Thanks, DanJS.

3mar · Answer

I like what you described DanJS.
I love the origin!

danjs · Answer

right, it is shifted 8 units to the right from h=8, and since b>1 it is compressed horizontally by a factor of b=2
