Answer:
(x+4)+(2x)
Step-by-step explanation:
9 x 9 = 81
81 - 21 = 60
60 / -6
10
Answer should be -4
since there is no other context, we can assume that x is -4.
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
