Ber [7]3 years ago
6 0

Answer:

         k + 9

x = --------------

              4

Step-by-step explanation:

To solve 4x - 9 = k for x, start by adding 9 to both sides.  You'll get:

4x = k + 9

Now isolate x by dividing both sides by 4:

         k + 9

x = --------------

              4

You plug in the values for x in each respective equation.

a) f(3) = 3 + 1 which equals: 4.
so, f(3) = 4

b) g(3) = (3)^2 - 3 which equals 9 - 3, which equals 6.
so, g(3) = 6.

hope this helps! (:
