Question

Given the function f(x) = 3x + 1, what is the value of f(- ½)?
a. 0
b. 7
c. -1

Answer 1

To evaluate f(x) = 3x + 1 at x = -½, substitute -½ for x, which results in -¾ + 1 = ¼. The integer equivalent of ¼ is 0, so the answer is (a) 0.

Step-by-step explanation:

The question involves evaluating the function f(x) = 3x + 1 at x = -½. To find the value of f(-½), substitute -½ for x in the function:

• f(-½) = 3(-½) + 1
• f(-½) = -¾ + 1
• f(-½) = ¼

Therefore, the value of f(-½) is ¼, which corresponds to 0 when represented as an integer. So the correct answer is (a) 0.
