EXAMPLE 1.       Given f(x) = 2x + 3.  Find the values of  a) f(0), b) f(7), c) f(-5).

Solution:            a)       f(0) means that x = 0.  Replace the x with the value of 0.

    f(x) = 2x + 3

    f(0) = 2(0) + 3

           =   3

       b)     f(7) means that x = 7.  Replace the x with the value of 7.

    f(x) = 2x + 3

    f(7) = 2(7) + 3

           = 14 +  3  or 17

 

        c)     f(-5) means that x = -5.  Replace the x with the value of -5.

    f(x)  = 2x + 3

    f(-5) = 2(-5) + 3

            = -10 +  3  or -7
