Question

suppose that the functions \\(r\\) and \\(s\\) are defined for all real numbers \\(x\\) as follows.

\
(x) = 3x + 2\\
\\s(x) = 6x\\

find the following.

\\(s + r)(x) = \\
\\(s \cdot r)(x) = \\
\\(s - r)(3) = \\

Find the following.

$$ (s+r)(x) = \text{}\(9x + 2\)\text{} $$

$$ (s \cdot r)(x) = \text{}\(18x^2 + 12x\)\text{} $$

$$ (s-r)(3) = \text{}7\text{} $$
