Question

Please help I don’t understand

Answer 1

Answer:

$y=-3\sqrt{x} +8$

Step-by-step explanation:

The question is asking you to write a function from the original function ($\sqrt{x}$) w/ the given conditions.

It wants you to make a function that reflects over the x-axis; should be mirrored with the original function.

y=-$\sqrt{x}$ does just that.

Then it wants a horizontal stretch by 3.

$y=-3\sqrt{x}$

Then move that graph up by 8 units.

$y=-3\sqrt{x} +8$

Please know the transformation rules for functions to understand what you are doing better.
