Given :
D2/5 ( ABC ) = (A'B'C')
D5/3 ( A'B'C' ) = (A''B''C'')
So, the scale factor of dilation between ABC and A''B''C'' =

Reflection over the y-axis = change
Compress by a factor of k = multiply by k
So, in your case, we first change the sign of the argument. Note that this has no effect, because f(x) is symmetric with respect to the y-axis:
Then, we compress the function, multiplying it by the scaling factor:
positive number times negative number is negative number "(+)(-) = (-)".
we change the mixed numbers to the improper fractions
