Nancy has to find the reflection of a point across the x-axis. How can she find the new coordinates without graphing the point? Is there a rule that she can apply to find it?

the only thing she needs to know is that in a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.

Step-by-step explanation:

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2
