Answer 16

The table below shows some values of f(x) and g(x) for different values of x.



Complete the chart and determine the solution of the equation f(x) = g(x)?
x = -2

x = -1

x = 1

x = 20

Answer 17

sorry plz post it as new...lunch time coming up for me here...

Answer 18

x f(x) = 2x + 24 g(x) = 5(0.5)x
-2 20 ?
