Describe the transformation relative to the parent function. f(x)=(9x)^4. correct answer will get brainliest

If you start from the parent function , the only transformation performed is . In fact,

In general, a transformation like results in a horizontal stretch. If k>1, the function is compressed, if 0<k<1, the function is streched. If k is negative, the function is reflected around the y axis, and then you apply the logic just described.

So, in your case, k=9, which means that the graph is horizontally compressed by a factor 9.

b.-4 units

all you   do is count how many times you move

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
