1. anonymous

h(x)= (x+5)^2

2. vera_ewing

Is that correct? @Nnesha ^^

3. Nnesha

f(x−h) here h is horizontal shift f(x) + k here k is vertical shift y=a(x-h)^2+k if h is negative graph will shift h unit to the right if h is positive graph will shift h unit to the left if k is positive graph shift k unit p if k is negative some unit down now look at the graph is it going up down left or right ?

4. Nnesha

|dw:1444354606202:dw|btw this is the parent function :=)

5. vera_ewing

It's going left

6. Nnesha

right so h should be negative or positive ?

7. anonymous

It ends up being (x-(-5)^2 though which makes it positive (x+5)^2

8. vera_ewing

Negative

9. Nnesha

right but the short cut is if its going left then sign should be positive and if it's going right then h should be negative (opposite ) and bec it's horizontal shift so number should inside the parentheses :=)

10. vera_ewing

(x+5)^2 So this is the answer? @Nnesha

11. Nnesha

right going left so h should be positive and h is horizontal shift should be inside the parentheses $\rm y= a(x-\color{reD}{h})^2+k$ :=)

Ok thanks!!!
