Question:
Solve the given problems related to the indicated examples of this section.
In Example 4, find the value of f (−2).
Data from Example 4
For a function f(x), the value of f(x) for x = 2 may be expressed as f(2). Thus, substituting 2 for x in f(x) = 3x − 7, we have
f(2) = 3(2) − 7 = −1
The value of f(x) for x = −1.4 is
f(−1.4) = 3(−1.4) − 7 = −11.2
