Explanation:

For each of the values of #x# simply plug in that value in #f(x) #

Hence when #f(x) = 15x +4 # and you put #x = -3 #

We get #f(-3) # then just replace each #x# in the expression you see with #-3#

#=> f(-3) = 15(-3) +4 = -45 +4 = -41 #

#=> f(0) = 15(0) +4 = 0 +4 = 4 #

#=>f(2) = 15(2) +4 = 30 + 4= 34 #
