Hi guys, I want to make sure that I did these problems on my study guide correctly.My final is tomorrow and I want to know I did this right.

14)if f(x) = 2x/5x-3, then f(2) is equal to:

a.2/3

b.3/4

c.1/2

d.3/5

e.-3/5

15.if f(x)= 2x^2-3 and g(x)= -x+5, then (fog)(x)=

a.-2x^2+20x+47

b.-2x^2-20x+47

c.2x^2-20x-47

d.2x^2-20x+47

e.-2x^2-20x-47

17.the function y= -x^2+IxI is:

a.odd

b.even

c.both odd and even

d.neither odd nor even

e.not symmetric with respect to the x-axis, y-axis, or the origin.
