Reflections Given: f(x) = x2

Reflection about the y axis: f(x) = (-x)2

Reflection about the x axis: f(x) = -(x)2

This is NOT a question but I just don't understand what this means! I will be very thankful if someone will be able to help me with this (reflections in PreCalculus grade 9)

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96
