4^10 and x^4 are the right answers
Y>50
y<78
so since u cant be less that 50 u have to be more and since u cant be taller than 78 u have to be less than 78
now:
y<78 but >50
C is the answer.
in the original function, when x=0, y=-1
in the new function, to make y=-1, x+3=0, x=-3. From the original 0 to -3 is a shift of 3 units to the left.
