Just wanted to see if I am on the right track with functions

1.g(x)=|2x-3|

complete the table. They give us the x I find g(x)
x= -2 g(x)=7
x= 0 g(x)=3
x= 1 g(x)=5
x= 3 g(x)=3
x= 5 g(x)=7


2. f(x)=x^2+2x

f(0)= 0
f(3)= 15
f(-3)= 3
f(a)= a(a+2)
f(-x)=x(x-2)
f(1/a)=(2a+1)/a^2

3. f(x)= |x|/x

f(-2)= -1
f(-1)= -1
f(0)= 0
f(5) = 1
f(x^2)= x
f(1/x)= 1/x^2

As always thanks for all the help

You are doing things correctly. I did not check all your answers (too many) but most are correct. g(1) is not correct.
