how to evaluate

Question

Given the function f(x) below, evaluate 3 f ( - 2 ) + f ( 1 )

f ( x ) = { 7 x - 2 } { 3 x ^ { 2 } - 2 x } { - 2 \sqrt { x } - 1 }

Answer 1

This simple but tedious--go slowly so you don't make careless errors......

Simply plug in the given value of x and do the arithmetic to get the function value. In the first case, don't forget to multiply by 3 when you get everything simplified.

Do this for each of the specified cases, and then add the results.

Note; You appear to have an unnecessary pair of brackets around the first exponent (3x^2). It is not wrong, but could lead to confusion. It is also possible that you copied something incorrectly, and that the brackets make sense---in the correct equation
