Rewrite the function to make it easy to graph using transformation of its parent function. Describe the graph. y = squ(25x - 25)

Mariana [72]

Parent function is y=√x
result is
-4+√(25(x-1))

-4 was added to whole function so translated 4 units down
it every x was multipied by 25 so horizontally stretched bya factor of 25
then, minus 1 from every x to move to right

so the blanks are
strech 25, 1 to the right, 4 down
