x     f(x) = 3x + 7  g(x) = 4)-x

               -2             16
               -1              4
                0               1

ganeshie8 · Answer

when x = -1, whats the value of g(x) ?

ganeshie8 · Answer

$$\large g(x) = 4^{-x}$$

ganeshie8 · Answer

plugin x = -1, what do u get ?

ganeshie8 · Answer

you get :  

$$\large g(-1) = 4^{-(-1)} = 4^1 = 4$$

which is same as f(-1), right ?

geekfromthefutur · Answer

right

ganeshie8 · Answer

that means, x=-1 is a solution to the given equations
