Answer:

  • Parent Function:  y=\sqrt{x}
  • Horizontal shift: right 3 units
  • Vertical shift: up 3 units
  • Reflection about the x-axis: none
  • Vertical strech: streched

Step-by-step explanation:

assume that y=\sqrt{x} is f(x)=\sqrt{x} and y=\sqrt{-2x+6}+3 is

g(x)=\sqrt{-2x+6}+3\\ f(x)=\sqrt{x} \\g(x)=\sqrt{-2x+6}+3

The transformation from the first equation to the second equation can be found by finding a,h and k for each equation.

y=a\sqrt{x-h}+k

factor a 1 out of the absolute value to make the coefficient of x equal to 1

y=\sqrt{x}

factor a 2 out of the absolute value to make the coefficient of x equal to 1

y=\sqrt{2}\sqrt{x-3}+3

find a, h and k for y=\sqrt{2}\sqrt{x-3}+3

a=1.41421356\\ h=3\\k=3

the horizontal shift depends on the value of h when h > 0, the horizontal shift is described as:

g(x)=f(x+h) - the graph is shifted to the left h units

g(x)=f(x-h)\\ - the graph is shifted to the right h units

the vertical shift depends on the value of k

PLEASE HELP ME! I NEED HELP, I ALREADY GOT 2 WRONG :(
ElenaW [278]

Answer: The snack shop sells granola bars for a lower price.

Step-by-step explanation:

First you should plug in the number of bars for each equation, if you get one bar from the snack shop the price would be $1.25, I'm going to fill in the table to help you better understand.

y= 1.25(2) 2.50

y= 1.25(3) 3.75

y= 1.25(4) 5.00

y= 1.25(5) 6.25

This table was all for the snack shop.
