Hi just need number 18 not 19 and 20

The graph of f(x)=|x| is reflected over the y-axis and horizontally compressed by a factor of 1/9. write a formula for function g(x)

What is 20+(5 x 2/5 )+ 3 show your work

Apolynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. if the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?
