Answer 2

The value of f(3) is (a) -11

The value of x = 3 corresponds to the following function on the piecewise

$\mathbf{f(x) = -3x - 2}$

Substitute 3 for x

$\mathbf{f(3) = -3\times 3 - 2}$

Expand

$\mathbf{f(3) = -9 - 2}$

Evaluate -9 -2

$\mathbf{f(3) = -11}$

Hence, the value of f(3) is (a) -11
