PLEASE HELP ASAP

19A)

f(x) = 2x ^ 2 + 1 and g(x) = 7x ^ 2 - 8

19B)

Find an equation of the tangent line to the graph of y(x) = 4 * (x - 1/x) ^ 2 at x = 2

An equation of the tangent line is y = _

Round your constants to 3 decimal places if needed.

f(x)=2x2+1andg(x)=7x28. Then f(f(x))=f(g(x))=andg(f(x))= Find an equation of the tangent line to the graph of y(x)=4(xx1)2 at x=2. An equation of the tangent line is y= Round your constants to 3 decimal places if needed
