Question:

How do you find the value of f(a), if #f(x)=3x-4#?

Answers

See a solution process below:

Explanation:

To find #f(a)# substitute #color(red)(a)# for each occurrence of #color(red)(x)# in #f(x)#:

#f(color(red)(x)) = 3color(red)(x) - 4# becomes:

#f(color(red)(a)) = 3color(red)(a) - 4#
