2-142.

Multiply each pair of functions below to find an expression for $f \left(x\right) · g\left(x\right)$ .

$f\left(x\right) = 2x, g\left(x\right) = \left(x + 3\right)$
Hint (a):
Multiply the expressions.
$\left(2x\right) \left(x + 3\right)$
Answer (a):
$2x^{2} + 6x$

$f\left(x\right) = \left(x + 3\right), g\left(x\right) = \left(x − 5\right)$
Hint (b):
Multiply using a generic rectangle.

$f\left(x\right) = \left(2x + 1\right), g\left(x\right) = \left(x − 3\right)$
Hint (c):
See part (b).

$f\left(x\right) = \left(x + 3\right), g\left(x\right) = \left(x + 3\right)$
Hint (d):
See part (b).
