Answer:
For , is translated units left.
For , is translated units down.
Step-by-step explanation:
The transformation of means that the graph shift to left by C units if C is positive number and shifts to right by C units if C is a negative number.
The transformation of means that the graph shifts up by C units if C is positive number and shifts down by C units if C is a negative number.
Here, in the transformation of , so, the function translates left by units.
Similarly, in the transformation of , so, the function translates down by units.
you would multiply the price by .20
example:
20% of $160
sale, 20% off
160 x .20 = 32
$32 is 20% of $160, $128 is the sale price
She used the associative property which should only be used with positive numbers (sorry if it isn't the answer you're looking for)
