• horizontal shift to the left 2 and vertical stretch by a factor of 3

• horizontal shift to the right 2 and vertical stretch by a factor of 3

If the yellow curve has equation $f(x)=x^2$  

• Then the blue curve is  $f(x)=x^2-c$  

• Then the blue curve is  $f(x)=(x+c)^2$  

• Then the blue curve is  $f(x)=(x-c)^2$  

• Then the blue curve is  $f(x)=x2+c$  

The original function has equation $f(x)=\frac{2}{3}\sqrt{x-7}$
